The alternative treemap chart view represents files as rings
Disk Usage Analyzer is a graphical disk usage analyzer for GNOME. It was part of GNOME Core Applications,[2] but was split off for GNOME 3.4. It was originally named Baobab after the Adansonia tree. The software gives the user a menu-driven, graphical representation of what is on a disk drive.[3] The interface allows for selection of specific parts of filesystem being scanned so a single folder, the entire filesystem, and even remote folders and filesystems can be scanned.[4] The graphical representation can be switched between a ring chart and a treemap chart so the presentation can be tailored to the specific content being scanned.[5]
In 2012,[6][7] Disk Usage Analyzer was rewritten in Vala.[8]
