{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"A zoomable sunburst diagram displays the hierarchical structure of the Flare dataset, with nodes sized by value and colored by top-level category. Clicking a ring zooms into that subtree while decreasing visible depth. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout and rendering, with transitions via `transition.attrTween` to animate arc geometry and labels. The SVG visualization imports data through the Observable stdlib and includes interactive hover tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b06dc28537b04e998b7465407c569154?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
