{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This example presents a zoomable sunburst visualization of hierarchical data from the Flare dataset, rendered as an interactive donut chart in SVG. The visualization uses D3 v5’s `d3.partition` and `d3.hierarchy` to compute angular and radial layouts, with `d3.arc` drawing each segment. Users click a node to zoom into that subtree, triggering a 750ms animated transition where `transition.attrTween` interpolates arc geometries and label transforms. The color scale uses `d3.interpolateRainbow`, and data is loaded via the Observable Stdlib `require` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/78122134c17b46f0927491ab7539119b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
