In order to visualise data, you need the data first. And beyond some very basic demographic data (if even that is available), I doubt you'd find anything standard worth visualising. AndyTheGrump (talk) 21:53, 19 April 2025 (UTC)Reply
@AndyTheGrump: At Wikidata there already are WikiProjects for countries. They all are trying to coordinate queries for national data in all kinds of fields. I do not think there is a strong connection between the data curation at Wikidata and data visualization here in Wikipedia. There must be something there. Economics? Tourism? Energy use? Education? Trade? Pop culture?
Steve Balmer former CEO of Microsoft has this project USAFacts where he presents all sorts of data visualizations at the national level for the United States. https://usafacts.org/ I am not sure where Wikidata and Wikipedia align for such things but if we found just one visualization model which was generally interesting, then we could mass post that in many articles in many languages. Bluerasberry (talk)17:03, 20 April 2025 (UTC)Reply
Regarding Wikidata, as I'm sure you are aware, it isn't WP:RS. As for mass-posting, that would appear to be grossly inappropriate, given that this is a draft English-language Wikiproject, with no mandate whatsoever to add content elsewhere.
While I can see real merit in this draft proposal, I have some reservations about its implementation: not least of which is its potential to encourage 'looking for data to visualise', rather than serving the interests of good article creation and maintenance as a whole. In my opinion, rather than looking for new data to 'visualise', the project should instead be looking at individual articles, and asking whether data already present (appropriate, due, reliably sourced data, that is) can usefully be presented visually. If, as a result of this, we conclude that such visualisations could be used more generally, we can then consider doing so. But we need to start from the premise that it is the data that matters, and that good 'visualisation' comes later, where is appropriate. AndyTheGrump (talk) 17:30, 20 April 2025 (UTC)Reply
@AndyTheGrump: Right, Wikidata does not fit WP:RS, but also, Wikipedia infoboxes also typically do not meet RS, and we have not reconciled that over the past ~25 years. Infoboxes for biographies contain birthdays, locations, marriages and other key data which often does not pass RS, and for cities everyone expects population, geography, GDP, and other primary source content which also fails RS. I think the way to address this is to face it directly, state the obvious that there are some expected data values that either we must include or recognize as conspicuously absent, and that we often fill our boxes with content from databases or primary sources.
We have consensus based on practice and precedent that non-RS data sources go in infoboxes, and going further, it is easy to imagine equivalents of infoboxes for subarticles or subsections. Check the right side of the article Economy of the United States - the infobox is full of primary content, and I count more than 20 data visualizations which themselves are mostly arbitrary, mostly primary source content. You might react that us editors organizing mass-posting is inappropriate, but if you are against standardization, then the default alternative is keeping content like this where random arbitrarily chosen graphics are on the side with no planning and no deliberation. We have been doing wiki long enough that now it is evident that we do not have, and will never have, the editorial labor pool to manually deliberate meaningful up-to-date data tables and visualizations custom for every article where they are needed. Also, I feel it is an inarguable fact that the quality of non-RS compliant datasets is going up quickly. While I am afraid that data can be co-opted for propaganda and by ill-will actors, Wikipedia could legitimately be a place to do some quality control and standardization to say which data sets are reliable, and which data visualizations ought to be standard as general reference information.
I get your intent when you say "it is the data that matters and visualization comes later", but as a matter of practicality, I think that we might be able to identify the data which matters by identifying which visualizations are super popular, noncontroversial, and widely discussed. I am not sure where this begins - maybe Our World in Data? maybe USAFacts? Maybe what people are doing on Wikidata? Maybe by looking at what visualizations are popular in Wikipedia articles.
I do not want to be transgressive in lowering Wikipedia's quality standards, but I do think it might be timely to admit that we already lack sourcing for some key data that we already include. Evaluating certain kinds of data visualizations as "standard" could help us streamline our fact-checking process for some data sources for visualizations. I would like your support in finding some way to mint some kind of visualization at scale from some primary data source, which we regard as trusted despite failing RS. Bluerasberry (talk)16:53, 21 April 2025 (UTC)Reply
I have absolutely no idea where you got the bizarre idea that data in infoboxes doesn't need to comply with WP:RS, but it is complete and utter nonsense. I suggest that rather than wasting your time posting TLDR misinformation, you take the time to familiarise yourself with core policy. AndyTheGrump (talk) 20:14, 21 April 2025 (UTC)Reply
I think that's a good idea. Currently, that page is at a niche place where nearly nobody will find it. Furthermore, I think things related to the upcoming Charts extension are relevant to this WikiProject so it would be best to have a subpage about it here.

Updated DV maps can have very different color progressions
Latest comment: 1 year ago4 comments2 people in discussion
Most OWID maps only get newer and more data when getting updated but some also get their color progression changed; examples:
This map has a color progression between 0 – 200+ for 2016 while the new version for 2019 has a different color coding, finely dividing between 0 – 50+ but not between 50 – 200+. Is there a specific good reason for that? Which version would be better?
This map (& png version) shows data for 2017 finely dividing between 0 – 5000+ with 8 colors whereas the new version for 2021 has different spans and just 7 colors, causing lots of countries having the same color instead of a finer distinction at 2k 3k 4k and 5–10k. In addition, when hovering on 5–10k+ no country seems to be highlighted so that 5-10k color seems redundant. So currently, it seems like the older map is better isn't it?
I wasn't implying so. It's more about that one needs to be cautious when updating charts because if they didn't just add more data, the prior image may be better despite of older data. Moreover, maybe there is a way to modify such charts, especially since the grapher tool is open source (it could also be just tinkering around with the SVG or editing the image in an image editor). Lastly, emailing OWID to ask about it would also be an option, maybe it wasn't intentional (e.g. I can't see why there is this redundant 5-10k color in the map and maybe they could consider adding the info 'no country had above 5k' if that's why it's there).
This thread is also there as an example or starter for things we could discuss here: which version of a data graphic is better and whether it should be updated or only updated if the coding/color-scheme/legend is the same or better. Prototyperspective (talk) 22:29, 7 June 2025 (UTC)Reply
Generally the newer data would be better in my opinion despite a few aspects that are less good. Running our own version of their grapher was something I asked about a few years back with no one at the WMF having the bandwidth. Doc James (talk · contribs · email) 22:45, 7 June 2025 (UTC)Reply
A way to make OWID charts only show the segments with data points?
Latest comment: 1 year ago4 comments2 people in discussion
Our World in Data uses the open source owid-grapher tool. Is there a way to make charts only show those parts of the y axis that have data points? See the example on the right: that the y-axis starts at 0 years instead of e.g. 40 years makes it difficult to distinguish the lines, trace any given line, and to see differences. Prototyperspective (talk) 19:24, 25 May 2025 (UTC)Reply
Yes but that skews the scales and thereby does make the data graphic somewhat misleading (even if it says it's logarithmic). The y axis should stay the same. Currently, the only option seems to be manually editing the graphic in an image editor. But only is that a hassle, it also doesn't zoom in to make the chart larger (same height but less y-axis) so as to make the line development and their differences clearer.

Hi folks,
I've created a bot that is undergoing approval called GraphBot, it is a migrator that turns the old graphs that use Template:Graph:Chart into charts. I thought that you might find this useful.
If I understood correctly, the bot can convert most of current graphs and is invoked by changing {{Graph:Chart}} to {{PortGraph}} after some delay. Please correct me if I'm wrong. One of the issues with it that I just noticed is that some articles like Llynfi power station just use <graph>...</graph> and the docs pages don't explain how to convert these.
Currently there is no support for <graph/> tags, but the reason for renaming Graph:Chart to PortGraph is to ensure that an user double checks that all attributes are supported by the chart extension (most importantly, whether they need control over height of the Graph, as the chart extension does not offer any control over that, but also for things like color scheme).

How to copy the terminology text of Our World in Data graphics?
Latest comment: 1 year ago2 comments2 people in discussion
Lots of visuals by Our World in Data have a large terminology text at the bottom when downloading them with the default option of "Include terminology definitions at bottom of chart" enabled. However, that often makes the charts too small and hard to see – text like that could instead be added to the file description and/or as a {{efn}} note in the file caption.
I suppose one could get the text by either typing it down manually or by opening the SVG file in a text editor – is there an easier way to get the terminology text to add it to the file description?

Do you guys need any assistance setting up banners, categories, project entries, etc.? I have noticed that this WikiProject lacks all these basic stuffs, and honestly, it has been quite dormant despite being brand new. I can help if you wish because I have done WikiProject renames and mergers in the past. —CX Zoom[he/him](let's talk • {C•X})08:24, 25 June 2025 (UTC)Reply
If you'd like to get involved, please go ahead. I don't see why these would be basics stuffs and how they would be useful here (as for the project entries, these are all on this page and many things are linked from there). Also given all the discussions above and recent developments (& edits), I don't know why you describe it as quite dormant. More participants and activity is very welcome. Prototyperspective (talk) 13:34, 27 June 2025 (UTC)Reply
Last subject-specific talk section was opened on 25 May, and Requested datagraphics page lies empty. For a new WikiProject, that's not very encouraging. But, hopefully, if the set up is completed, there will be more activity here. —CX Zoom[he/him](let's talk • {C•X})15:34, 27 June 2025 (UTC)Reply
@CX Zoom: I don't think this is the kind of wikiproject that will make much (if any) use of the banner tagging and assessment system, since it's focused on improving a certain type of content (graphs) across all pages rather than generally improving articles on a particular topic. More like WP:URA than WP:MILHIST, in other words. Also the start of the wikiproject was a bit unusual in that it was in anticipation of an (then) upcoming new tool which has only recently become available. So now we are able to start work. – Joe (talk) 10:12, 28 July 2025 (UTC)Reply
Some sort of drive to eliminate broken graphs
Latest comment: 1 year ago2 comments2 people in discussion
Sounds like a good idea! However, there are also issues with the new extension and I don't know to which fraction of graphs this is relevant – see e.g. mw:Extension talk:Chart#Wishlist and the section right above it. People can use the script or the bot for converting graphs that are linked under 'Things to do' on this project page. Prototyperspective (talk) 22:36, 27 July 2025 (UTC)Reply
thanks for the link, the video recording is very insightful.
for everyone's benefit, i summarize here what i have found within wikimedia foundation (WF) and Our World In Data (owid)
regarding a chart library for WF: the requirements and records of decisions based on new learnings from 2024 through aug 2025 can be found here
In a nutshell, the decision is to use apache echarts, over solutions such as other js libraries (vega-lite for instance) or owid grapher. This decision is based on scalability, security, ease of maintenance, necessity of open source project with large support for community, and constraints around contributor help (balance between innovation and consistency / security). The decision leaves the door open to future migrations to owid-grapher or other js libraries.
documentation states that they are open to help but will focus on their requirements first. owid focuses on development data which may be a limited use case for wikipedia.
I am looking at ways to contribute to this joint project since it is needed (and quite complex ), but it does not seem straightforward: here is an example of someone trying to help owid but not being able to yet.
We are still working on address concerns raised by EN WP before pitching the all Commons images solution to the EN community again.

On EN WP it loads fine when I am in incognito mode. But when I am logged in, the first time I open it stalls on the loading screen, but with a refresh it then loads. Not sure if others are experiencing this as it might be an interactive with another gadget or something. Doc James (talk · contribs · email) 23:09, 1 October 2025 (UTC)Reply
@Doc James: Same problem in Firefox, Windows 10 Pro PC whether I am logged in or not. Solved by reloading it.
The blue bar at the bottom is a little too tall. It encroaches on the timeline slider.
It works for me in Firefox/macOS in an incognito window. That suggests that there is some gadget/user script conflicting with it. It doesn't work at all in mw:safemode (this is expected, since safemode turns off the script for the interactive map along with all the other maps), so it might be necessary to use mw:Help:Locating broken scripts#Other ways to identify broken scripts.
Doc James. This is weird. I was using the OWID-slider on the project page. Which has the exact same code as here on the talk page. I checked again, and tested again. Does not work whether logged in or not. In Firefox on Windows 10 Pro PC.
Strange as it reacts differently for me. On firefox it does not load when I am logged into my main account, it works when I am logged out, and it works when I am logged into a new account. So it is something we have turned on on our accounts. Doc James (talk · contribs · email) 14:41, 2 October 2025 (UTC)Reply
Yes, it is working on both pages whether logged in or not.
Blue bar with "Return to article" needs to be halved in height. It covers part of the timeline slider. If I increase the font size it will cover "Media credits".
Also, spaces, not dashes, should be used in file names to separate words. And longer, clearer file names are better for search engines. I have file moving rights, and so I changed
Year should not be added to filenames for images that will be updated. Maybe I should return the year since it is part of a series. I see the series when looking at the template wikitext source code:
Can you send me a picture of the formating your seeing? This is within firefox I assume? Formats well for me.
The naming can be changed but realize that these names are applied to hundreds of files and we should keep them insync. We have the following for example:
If the files are moved we need to keep redirects for the tool to function. If redirects are lost the whole thing will break. But when we do a mass reupload everything will get super confusing, so please do not do manual renames for now.
Okay was able to recreate the issue, it just occurs on firefox when the screen is much wider than it is tall. Does not occur on Chrome. Will add it to the list of fixes needed.[2]Doc James (talk · contribs · email) 19:52, 2 October 2025 (UTC)Reply
And it would make the individual images accessible to more people. Search engines outside Wikipedia also use Commons images in their image search results.
Formatting? Of the blue bar? To me it just looks like a 2-line-tall blue bar filled with a 1-line phrase "Return to article". I am suggesting narrowing it to a 1-line-tall blue bar.
It might be because there is padding based on em units in the div or table housing the blue bar or banner. If so, I suggest changing the padding units to pixels.
And use only the minimum number of pixels necessary to separate the phrase "Return to article" from the top and bottom edges of the blue bar, and still be legible.
Someone changed the file name back. That is fine. I see now that people can find the OWID sliders via the template name in the {{owidslider}} template wikitext in the above OWID slider:
The list names are the same as the template names except the dashes have been converted to spaces.
The template names need the dashes converted to spaces. The list may have lapses in maintenance, but the template category will be up to date. And if the template names have spaces, then they will be more easily found via search engines on and off Wikipedias. And thus more used. They will soon be copied to pages off Wikipedia too since they are free graphics like everything else on the Commons. --Timeshifter (talk) 07:32, 3 October 2025 (UTC)Reply
I don't know how to use it though. Need to be able to search for {{owidslider or Template:Owid/ since those are parts of {{owidslider}} in the wikitext for an OWID slider graphic.
A lot of work. Pages that used any of the templates have been updated too, hopefully. Is there a page that explains step by step how to upload everything necessary? And all steps to create a template? --Timeshifter (talk) 07:52, 4 October 2025 (UTC)Reply
Okay uploaded, but it does not work how it should.[5] I want the image shown via "file=" not to load when clicked but instead all data should come from "list=". Need to fix this. Doc James (talk · contribs · email) 12:26, 3 October 2025 (UTC)Reply
OWID is very confusing as to how to get only the latest year. Reference has the only way I have found so far. Other methods get multiple years per country.
@Doc James: Thanks for the link. I looked at a few of the broken ones. At least the opening map. They may have a similar problem. The healthcare cost interactive map above is showing only the available 2023 data, I believe.
I matched the 2023 countries listed in the table here:
You will notice that it is set to 2022 as that is the year with full data. The 2023 graph you post above shows mostly data from 2022 and thus is a misleading. When you open the interactive graph you can move to 2023 and it shows the countries were 2023 data IS available. IMO this is better / more honest. Doc James (talk · contribs · email) 15:56, 19 October 2025 (UTC)Reply
That's good. Being that this is an article and topic I have been interested in for a long time, there are a few things I would really like to see:
A link back to the OWID source. Number one reason being that the source provides more options, and I like those options:
Number 2: Everything must be verified in a Wikipedia article. WP:Verify. I don't want to count on individual editors to do that. Indirect ways back to the source don't count. Like the media credit link back to an individual image, and then a link from there on the Commons back to the OWID page. Technically all images on Wikipedia have to be referenced. Though many images in articles use the roundabout way, article editors can delete images without direct references if they so choose.
It would be nice if the bot provided such a reference. Perhaps a "Source (off-wiki)" link next to "Media credits".
@Doc James: Most people aren't going to do it. It's not intuitive to find the reference since it is not like images where one just clicks the image and is taken to the Commons where there is a link to the source.
One has to click on the map, and then click "Media credits" to be sent to a single image page. It is not intuitive that the source for a single image is the source for the interactive map. And it is more steps. --Timeshifter (talk) 05:49, 20 October 2025 (UTC)Reply
@Doc James: Duh, that's funny. I guess I long ago (20 years on Wikipedia, Wikia/Fandom, Shoutwiki) stopped using that since it is not always available, and it is a lot easier to right-click the image (a much bigger target for a shaky mouse). If there is no caption, then it is not there. I stopped using it so long ago I forgot it existed. Probably true for others too.
And on Fandom an "i" link to the file description page shows up upon hovering over the image. Nothing in the right corner ever, even with a caption. And on Shoutwiki there is neither. Right-clicking is the only way.
Right-clicking the graphic takes one to 2 different places depending on whether there is a caption or not.
With caption one is taken to the expanded single map.
Without caption one is taken to the Commons file description page for that map on top. There one finds a reference source for that single image. But there is no way to know ahead of time that you will be taken to the interactive source, instead of just a single image source. That single image may not be on top since OWID shows the 2023 latest available year map on top, not the 2022 map that is on top here.
Since these interactive maps will probably be copied to other wikis, I think there ought to be an easy way to get to the source interactive map. There ought to be an easy way to the template too:
There is plenty of room for both of those links below the map on the same line as "Media credits". Maybe point your programmer here to see what he thinks. Here is the graphic without a caption:
I noticed another problem. "Upright=1.6" sizing does not work without the caption. So I used 500px.
And it is showing the transparent SVG on top. Which makes the text above the map illegible in dark mode.
I added "border" since there are no caption borders:
|file = [[File:annual healthcare expenditure per capita, World, 2022 (cropped).svg|500px|border]]
The timeline slider does not show up when clicking the arrow on the graphic without a caption.
I think viewing the template pages is a huge load for the Commons servers. Maybe just link to all the images, and not show them. If people want to see them they can click on the graphic, or on the individual links. I don't think all the component images need to load on the template page itself:
On the graphic I believe the yearly image only shows up if you slide to that year. Same for the regional maps. If not, they should. To save server bandwidth. --Timeshifter (talk) 07:03, 21 October 2025 (UTC)
--Timeshifter (talk) 07:03, 21 October 2025 (UTC)Reply
We only load the region folks are looking at. We load all within a region to make sliding work. But we only fully load one image. It is complicated.
With respect to all component images, they need to be listed. Not sure if there is a way to list them but not show them. But meh.
@Doc James: Even if captions are generally placed I want people to go look at the OWID page. It has many more features and options. So I want a more direct link next to "Media credits". I also would like the link to be clear as to why one should go there. Something like: "Off-wiki source with more features". It will also build up more support for more features on Wikipedia, too, hopefully. But if not, at least those people who are interested can go there easily and directly. For some readers who want to be sure about what I am talking about:
The Implications of "Grokipedia" in Terms of Scale
Latest comment: 9 months ago13 comments3 people in discussion
The upcoming xAI project "Grokipedia" is direct competition to the integrity of the Foundation's core objectives. I believe that it warrants a discussion within the project about the need for the Data Visualization widget to increase in scale. We may need to consider a full, in-house, AI Model that is proprietary to the foundation and tailored specifically towards core objectives. -- Sleyece (talk) 23:48, 5 October 2025 (UTC)Reply
Given the mathematically-proven inevitability of 'hallucinations' within LLMs, [6] I can't see how using any 'AI model' based on such technology could possibly be compatible with 'the integrity of the Foundation's core objectives'.And nor can I see what exactly this AI is supposed to do for data visualisation anyway. As for 'Grokipedia' it is, as of now, hypothetical, and could very well turn out to be yet another of Musk's proposals that never sees the light of day. AndyTheGrump (talk) 01:11, 6 October 2025 (UTC)Reply
I'd start by describing what this particular 'ball' is supposed to be doing in regards to data visualisation on Wikipedia, and why you think it is necessary. AndyTheGrump (talk) 13:41, 6 October 2025 (UTC)Reply
You don't seem to understand the difference between AI hallucinations and emergent behaviors. So, I don't think explaining a system to you is going to go anywhere productive. I'll just post demo in the gadget space on OWID. Maybe show is better that tell with this type of thing. Also, I just said we need to be aware of the Grokipedia project that is pending. I'm getting a lot of hostility for no reason. -- Sleyece (talk) 18:11, 6 October 2025 (UTC)Reply
In as much as I'm hostile to the use of AI (more specifically LLMs) to generate content for Wikipedia, my views seem to be very much aligned with those of the rest of the community, which is currently faced with a spate of ChatBot-generated garbage. And as far as I'm aware, Musk hasn't said anything regarding data visualisation specifically in regard to his hypothetical project, which makes me wonder whether it is even relevant. AndyTheGrump (talk) 20:02, 6 October 2025 (UTC)Reply
I didn't say anything about having an LLM write articles. You're clearly bringing your hang ups with AI in total to a thing that was very limited in scope. I was suggesting an AI tool to check for data visualization errors and improvements in a similar way to how bots have preserved the integrity of Wikipedia for years. I understand the frustration of large edits being a copy/paste from ChatGPT or whatever, but that's not my angle. I wasn't trying to start a generalized debate on LLMs. -- Sleyece (talk) 02:59, 7 October 2025 (UTC)Reply
So what was all the waffle about Grokipedia in the first post about then? If you'd given a simple description of what you intended (and left out the gratuitous comments about my username), none of this extended discussion would have been necessary. If AI can reliably be made to offer advice on data visualisation content, to be looked at by contributors and then actioned if necessary, that might well be useful, though I'm of the opinion that compared to the endemic issues we have with unsourced data, original research etc in the data such visualisations are all-too-frequently built around, it might not be seen as a priority. AndyTheGrump (talk) 11:21, 7 October 2025 (UTC)Reply
Oh, in the first post I just meant to imply a sense of scale. Like if Grokipedia does turn out to be a legitimate competitor in the space, and not just a side project Elon forgets about in a few weeks, we could scale this up w/ increased priority as needed. I agree that this may not be seen as a priority right now, but things can change quickly. -- Sleyece (talk) 13:30, 7 October 2025 (UTC)Reply
I too don't really see the ball here. On the subject of AI, i too think we should be very conservative about AI usage within the encyclopedia, but at the same time, i'm seeing a lot of door-to-door encyclopedia salesmen, who haven't realized yet they have lost their jobs to the Internet. With which to say.. the interaction method people are clinging on to here for dear life (a webpage), has already been replaced (conversational/AI). I hate it too, but just looking around tells me all I need to know about where this is heading. If we want to not end up like the encylcopedias of old, we should be doing a lot more experimentation than we have been willing to do.

OWID slider. Problem with height of blue bar at bottom
Latest comment: 9 months ago15 comments2 people in discussion
Doc James and all. I mentioned this higher up. Blue bar with "Return to article". See screenshots of bottom of the slider map:
Could eliminate the blue bar and put an X button to the top right or top left next the image. That and moving the top regional/world menu to the side would allow room for a bigger map without scrolling. --Timeshifter (talk) 01:10, 9 October 2025 (UTC)Reply
@Doc James: Could put X buttons adjacent to the map on both the top right and top left. Then people couldn't miss it on desktop. In case they have scrolled left or right to a menu or other added info. --Timeshifter (talk) 13:10, 9 October 2025 (UTC)Reply
@Doc James: The overlap problem is gone. Thanks to all involved.
Maybe point the programmer to these threads. There are some ideas of interest. Like the wrapping info and help links.
I would like to see bar height down to one line. Or eliminated, and replaced with X's on each side adjacent to the map. Every bit of increased space allows the map to expand. I notice that the map expands when allowed. For example, when I go full-screen. Maps are almost always better the larger they are. --Timeshifter (talk) 03:00, 17 October 2025 (UTC)Reply
Moving the top regional/world menu to the side would allow room for a bigger map. The code allows the menu to go above the map on narrower screens. --Timeshifter (talk) 03:36, 17 October 2025 (UTC)Reply
You mean you want multiple graphs to work well side by side?
Yes, this is what I want: "moving the region dropdown on wider screens".
We already have the ability for side-by-side interactive maps. See below, and look at the wikitext. Narrow your screen to see them wrap and stack. I would think the regional menu could similarly be initially to the side. And similar CSS used to make it wrap and stack on narrower screens.
I fixed it there. I experimented here. I noticed that if the image alignment is different between the 2 file= image links, then there are alignment problems either before or after wrap and stack.
I prefer to set both to "none" in case the interactive maps end up not being together later. With "none" the interactive map does not float right or left before activation.

SVG crop of OWID slider maps to move bottom text to "i" button
Latest comment: 9 months ago15 comments2 people in discussion
We now have a tool that allows us to crop SVGs.[8] As such am trimming the displayed images to remove the difficult to read small text at the bottom.[9] People can find it under the i when opened or on Commons. Doc James (talk · contribs · email) 19:21, 9 October 2025 (UTC)Reply
@Doc James: - Look at my user page in the Gaza section to see the only way I could figure out how to keep text with specific background colors to work in light and dark mode. I have limited understanding of CSS. So there may be better ways. I used this in the CSS: !important;
If you look at all the OWID slider threads on this page you will see one common problem of text not appearing correctly, or at all, in dark mode. For example, the "i" button text, and the "select region" menu above the map.
Another problem is the bottom blue bar (with "Return to article") being too tall. See relevant thread above.
Also discussed: the "select region" menu would probably be better on the right or left, so that there is room for a larger map on desktop monitors. The top menu could wrap to the top in narrower screens. See relevant threads above. --

And we have a programmer slowly working on fixing these things. But yes it takes time.
But I don't see options for light and dark mode. So I installed this Firefox addon to toggle between light and dark modes. But different from Wikipedia's light and dark mode.
Go here MDWiki:WikiProjectMed:OWID, make sure you are using Vector (2022) under preferences, than play the interactive graph, and for me it now works fine on Chrome and Firefox. We have not rolled these changes out to EN WP yet as waiting to finish fixing the blue bar issue before asking for an update here.

Oops. I see the light and dark mode selector at the bottom of the right sidebar. I struck out my incorrect observation about that above.
I am using Firefox browser with Vector 2022 skin. I can now see the regional menu text, and the info text, in both light and dark mode. I am looking here:
Yearly healthcare expenditure per person (total public and private)
Health expenditure government expenditure
Are there any instructions on the Commons on how to find them, add them to English Wikipedia, adjust parameters (like sizing, or moving them to the left, right, or center)? I had forgotten almost everything we had discussed above. There is nothing intuitive about any of this. There needs to be a single instructional entry page on the Commons for all these interactive OWID graphics.
And how do I tell where the above 2 interactive maps are being used on English Wikipedia?
How do I tell where any of the health ones are being used on English Wikipedia?:
And I am confused about gadgets. Can anybody now see the OWID interactive graphics on English Wikipedia and on the Commons, without installing anything? --Timeshifter (talk) 01:30, 11 January 2026 (UTC)Reply
Yes fully live on EN WP for everyone.
There are some instructions here Template:Owidslider but if you want to add to them or include an FAQ that could be useful.
Now some simple instructions are needed. Linked from that page. I don't have the health, time, or energy to do that. And anyway, you are the expert, not me.
I notice that only the latest map with all the countries updated (via media credits) in the slider shows where the slider is being used on Wikipedia. See example here:
But not earlier maps, nor the 2023 map (since only some countries have 2023 data).
Does the slider wikitext have to be updated yearly? Would be nice if it was automatic, though I could see how that would be difficult with maps not showing the same latest year for each country. I am happy with latest available year. I notice that it pulls up the 2023 map, but it shows the 2022 map first. So I guess it is automatically updating. Just not the starting map that shows in the Wikipedia article. --Timeshifter (talk) 18:54, 11 January 2026 (UTC)Reply
OWID data graphics that aren't available anymore at source
Latest comment: 6 months ago8 comments4 people in discussion
There is a problem of data graphics by Our World in Data (biggest source of CCBY data visualizations) not being available anymore. Over time, I've aggregated quite a number of such cases. I could not find out the reason why they're not available anymore for any of these. I will list most of such files I found below (see the links in source field of the file descriptions).
Is there a way to find out why they're gone? Maybe this means the data was very flawed and that the data graphics should be removed from where they're used and a warning be added to the file description on Commons.
c:File:Adolescent birth rate in women aged 10-19 years, OWID.svg – unlike the other files, in this case two similar files still exist and the link still works to point to one of these: the source link now shows the map for 10 to 14 years instead of 10 to 19 years but that's quite a difference and I'd like to (& can) update this heavily-used map only with a map that shows data for 10-19 years olds (note on OWID in the description it still says "Adolescent birth rate (per 1,000 women aged 15-19 and 10-14 years)"; the map has been split so there now is a separate 15-19 years olds map and ideally one would have 10-14, 15-19 and 10-19
These aren't all cases. I found these because I was categorizing and updating files on Commons.
One idea would be to ask OWID why these are not available anymore per mail. For now, I'll ping @DanyX:, Head of Engineering at Our World In Data – do you know more? (If you prefer email, you can also mail me.) By the way, you'd be very welcome if you'd like to join this wikiproject. I also have a few other questions about OWID visualizations but I'll ask them separately at later times :) Prototyperspective (talk) 23:45, 3 February 2026 (UTC)Reply
I know they reorganize some parts of their website from time to time and that sometimes this causes content to then be located at another place of the site where sometimes the links in the source field break.
However, for these cases above the content is nowhere to be found on the website anymore (maybe there is 1 or so exception here that I missed) and the issue here is largely not that the source can't be found anymore – as a problem of verifiability – but these two problems:
why was the content removed (again, maybe the data was so bad they decided so and Wikipedia should probably also remove the file from where it's used for the same reasons)
it looks like these files won't be updated anymore but they would be useful (so it would be great if they could be brought back and then be updated at some point)
Daniel here, Head of Engineering at OWID. Yes, we sometimes reorganize our charts and remove charts for various reasons, some of which are:
Data quality issues were surfaced
They are no longer updated by the original source and we feel they are very outdated
We don't use the chart anymore in our writing
We have long known that this can be an issue for other downstream users like Wikipedia, which is why we created a stable, timestamped archive for all our charts.
You can find the links to the archive by scrolling down to the bottom of the page, in the "Full citation" section. For example, as of today, the archived chart for life expectancy was last archived on October 22, 2025. The link also shows up when you click inside the chart on Share -> "Embed this chart" where IFrame fragments are given for both the current version and the latest archived version.
Because charts are now archived, we can curate our current chart catalog according to our editorial needs without breaking existing uses of those charts, which will continue to work via the archive. Unfortunately, the charts you mention were removed before our archive was in place and so you will have to rely on the internet archive to see these.
Thank you for the explanations. It's great to see you set up an archive at OWID.
It would however be great if you added some reason when data graphics are removed at least for those where the reason was data quality issues and/or set up some list of data graphics with data quality issues with if possible at least a short explanation as to what the likely problem is.
That is because these data graphics are used on Wikipedia and if there's data quality issues you identified, we'd like to know so as to consider removing the data graphic from where it's used or adding some note about where/how the data may be flawed.

@Doc James: This might work since it is the talk page for the main interactive OWID page on the Commons:
It's the talk page of the wish "Make the Chart extension beginner-friendly". If you have some experience with the Chart extension, you may want to participate there. Prototyperspective (talk) 14:03, 19 February 2026 (UTC)Reply
Embed interactive charts from Our World in Data
Latest comment: 2 months ago2 comments2 people in discussion
Unfortunately, the visualization you’re looking for doesn’t exist, or you don’t have permission to access it. If you’ve created this visualization or it has been shared with you, launch the editor by signing in:
I met with one of the founders today. They are interested in collaborating with us and potentially providing us pro bono accounts. Once the graph is created, downloading the SVG would be under an open license. We are also looking at the possibility of interactive embeds from them. These interactive embeds could potentially be run on our own servers and than pulled into Wikipedia as iframes. We will need to build that infrastructure :-) Doc James (talk · contribs · email) 16:12, 2 July 2026 (UTC)Reply
@Doc James: That's great. I would like an easier form for the US choropleth maps that ends up with the same result:
