{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualization displays hierarchical data from the Observable flare dataset through a radial partition layout. The visualization uses D3 v5’s `d3.arc`, `d3.partition`, and `d3.hierarchy` APIs to render SVG paths and labels. Clicking on a partition smoothly zooms into that node using `transition.attrTween` with interpolated arc angles, while a central circle resets the view. Colors are assigned via `d3.scaleOrdinal` with an interpolated rainbow palette, and labels rotate to remain readable throughout the animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5fadcf59a22241a2a1cd63d55ce18888?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
