{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This example shows a zoomable sunburst visualization of hierarchical data from the Observable Flare dataset. Users click on arcs to zoom into deeper levels, and a central circle returns to the root. Built with D3 v5, it uses `d3.partition`, `d3.hierarchy`, and `d3.arc` for layout, with `d3.scaleOrdinal` and `d3.interpolateRainbow` for coloring. Transitions animate arc paths and labels via `transition.attrTween` and `d3.interpolate`. The SVG renders with clickable paths and a reset circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/86438d38131f4898943910d3de714f39?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
