{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualizes the flare dataset, a hierarchical collection of file sizes. The visualization displays the hierarchy as concentric rings, where each ring segment represents a node, with size proportional to its value. Users click on a segment to re-center the view on that subtree, and click the central circle to zoom back out. Built with D3 v5, it uses `d3.hierarchy` and `d3.partition` for layout, and `d3.arc` for rendering paths. Interactions are animated via SVG `transition` and `attrTween` methods, with color mapping from `d3.scaleOrdinal` and `d3.interpolateRainbow`. The data is loaded from the `@observablehq/flare` dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/553f1581b1c247f7bde12198c5f52dc1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
