{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"A zoomable sunburst chart displays hierarchical data as concentric arcs, where clicking a segment zooms in to show it as the new root. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the layout, with a color scale based on `d3.interpolateRainbow`. Clicking triggers a smooth 750ms transition via `transition.attrTween`, animating arc paths and labels. The hierarchy comes from the Observable `@observablehq/flare` dataset, rendered as SVG with interactive hover tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f31afbdf221c451f95b2e37ebc92f409?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
