{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualizes hierarchical data from an Observable flare dataset, letting users click arcs to zoom into nested categories. Built with D3 v5, it renders the chart as an SVG using `d3.partition` and `d3.arc`, with animated transitions via `transition.attrTween` that smoothly interpolate arc positions. Colors derive from a rainbow scale based on top-level children, while labels dynamically appear or fade based on arc visibility. The example also includes a central reset circle to navigate back to the root.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff3f6538fef1437795495760c756c4dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
