{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst chart visualizes hierarchical data, displaying nested nodes as concentric arcs with color-coded categories and interactive labels. Clicking an arc zooms into that subtree, while clicking the center circle returns to the root. The visualization uses D3 v5’s `d3.partition` layout, `d3.arc` for path generation, and `d3.transition` with `attrTween` for smooth animated updates. Data is loaded from the `@observablehq/flare` dataset via the Observable stdlib, which the code fetches using `require()` before rendering the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/65a4e0ad461a47e8904147df588fb1c7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
