{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"A zoomable sunburst diagram displays hierarchical data as concentric arcs, with click interactions drilling into nested levels and animating transitions via `d3.transition` and `attrTween`. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render SVG paths, with `d3.scaleOrdinal` and `d3.interpolateRainbow` for color encoding. Data comes from the `@observablehq/flare` module requiring the Observable standard library. Labels rotate and fade based on arc visibility, and the visualization loads data asynchronously using `d3.csv` fetches.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/adcf7c804149418e87bf518328643510?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
