{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"The D3 v5 Zoomable Sunburst shows a hierarchical dataset of the Flare visualization library (loaded via the @observablehq/flare module) as a multi-ring sunburst chart. Clicking an arc zooms in to reveal its children, with smooth transitions applied to the arcs and labels via `transition.attrTween` and `d3.interpolate`. The visualization is rendered as SVG, uses `d3.hierarchy` and `d3.partition` for layout, and `d3.scaleOrdinal` with a rainbow palette for coloring top-level categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d092cd0119154a72b3439ceda35a3e29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
