{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This example shows a zoomable sunburst visualization of the Flare software package’s class hierarchy, with arc size encoding class value and color assigned by top-level category. Clicking an arc zooms into that subtree, animating the radial layout transitions. The code uses D3 v5’s `d3.partition`, `d3.hierarchy`, `d3.scaleOrdinal`, `d3.interpolateRainbow`, and `d3.arc`, with transitions driven by `transition.attrTween` and `tween` on path data. Data loads via the Observable stdlib `require` for `@observablehq/flare`. Rendering uses SVG paths and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/775e651bf45e467da15700e4e643ca32?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
