{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"An interactive zoomable sunburst visualization displays hierarchical data from the Observable Flare dataset, where clicking on an arc zooms into that subtree. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render SVG paths with animated transitions via `transition.attrTween`. Color is assigned by a `d3.scaleOrdinal` interpolating rainbow hues across top-level children, while labels rotate and fade based on arc visibility. Clicking the center circle returns to the root level.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/164aeb3a6c24449d8ed0551605b4775b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
