{"version":"1.0","type":"rich","title":"Zoomable Sunburst","description":"A zoomable sunburst chart visualizes hierarchical data from the Flare dataset, which is loaded asynchronously via the Observable standard library. The chart initially displays the full hierarchy, and clicking on any node smoothly animates it to the center while zooming into its descendants. Implemented with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the arcs, with click transitions driven by `transition.attrTween` for geometry and opacity interpolation. The color scale uses `d3.scaleOrdinal` with an interpolated rainbow range, rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/105a215908814f4e8180ff648d197263?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
