{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"The zoomable sunburst visualizes hierarchical data from the Observable Flare dataset as concentric arcs, where clicking a node recenters and rescales the view on that subtree. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout and rendering, with smooth 750ms transitions driven by `transition.attrTween` and interpolation of arc geometry. Color is assigned per top-level branch via a rainbow ordinal scale, and labels rotate radially with visibility filtering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa93c3dffdec470f9476be2189894218?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
