{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualizes the structure of a hierarchical dataset, using nested arcs to represent the flare data from Observable’s `@observablehq/flare` library. Each level of the hierarchy is depicted as a ring, with arc segments sized proportionally to the data values. Clicking on a segment triggers an animated transition using `transition.attrTween` and `d3.interpolate` to smoothly re-center the view on that node, showing its children in greater detail. The visualization is rendered with SVG inside a circular partition layout, and the code uses `d3.hierarchy`, `d3.partition`, and `d3.scaleOrdinal` with the `interpolateRainbow` color scheme to distinguish top-level categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e1f3b9786564f74aa9cda00c1effb82?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
