{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst chart visualizes the hierarchical structure of the Flare data library, using D3 v5’s `d3.arc`, `d3.partition`, and `d3.hierarchy` APIs. The root hierarchy is loaded via an ObservableHQ library (`@observablehq/stdlib`), and each ring segment is colored by top-level category with proportional arc lengths. Clicking a node smoothly zooms the chart via `transition.attrTween` and `d3.interpolate`, animating both arc geometry and label rotation. The SVG rendering includes hover tooltips showing the full path and numeric value for each leaf.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7953d68ab3ea4fa9ad6a5eafbb906a42?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
