{"version":"1.0","type":"rich","title":"Fork of D3 v5 Zoomable Sunburst","description":"This interactive sunburst chart visualizes hierarchical data from the Observable Flare dataset, with each arc representing a node and its size proportional to its value. Users click on arcs to zoom into that subtree, triggering a smooth 750ms animation that repositions and rescales all visible elements. The visualization is built with D3 v5, using `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, while color encoding is derived from a rainbow interpolator applied to top-level branches. Transitions employ `transition.attrTween` with an interpolator to animate arc paths and labels during zoom interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f12240c477f34fddac530df354d58845?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
