{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, displaying nested arcs whose size and color encode node values and category. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions animating arc paths and labels via `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the SVG layout, while a rainbow color scale distinguishes top-level branches. Data loads asynchronously from the Observable Flare module using `observablehq/stdlib`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bd35137b47e8404e9b7ac776354fab0f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
