{"version":"1.0","type":"rich","title":"Hierarchical Pie Chart","description":"This hierarchical pie chart visualizes the file and directory structure of a Flask project. Each ring level represents a directory depth, and the angular extent of each slice is proportional to the number of lines and bytes in that file or folder. Clicking a slice triggers an animated rebasing that zooms into the selected hierarchy level, recalculating angles and radii to make that slice the new root. Hovering reveals a legend with details, and the SVG uses smooth transitions to adjust arcs, illustrating the nested codebase composition.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4710330?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
