{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This visualization renders the Flare software package hierarchy as a zoomable sunburst, where each arc segment represents a node and its size encodes the node’s value. Users can click arcs or the central circle to drill down or back up through the hierarchy, with animated transitions handled by `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and draw the layout in SVG, while `d3.scaleOrdinal` with `d3.interpolateRainbow` assigns colors to top-level branches. The data is loaded asynchronously from the `@observablehq/flare` module via the Observable standard library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e23bf11ce7234df38c3d01eb9439fb32?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
