{"version":"1.0","type":"rich","title":"Bubble Chart","description":"A bubble chart displays the Flare class hierarchy, encoding each class’s count as the area of a circle. Circles are packed tightly with d3.pack, colored by package using d3.scaleOrdinal and d3.schemeCategory20c, and labeled with clipped text. The code loads CSV data via d3.csv, builds a hierarchy with d3.hierarchy, and renders SVG circles, clipPaths, and titles. It follows an implementation by Jeff Heer and is forked from mbostock’s block.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-dcb8fd22e376cce85372884cc096a8ab?mode=embed\" width=\"960\" height=\"960\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":960,"cache_age":3600}
