{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst visualizes hierarchical data, showing the proportion of food categories across multiple cities. The data is loaded from the `@observablehq/flare` dataset and rendered as an SVG with animated transitions. Users can click on arcs or the central circle to zoom in and out. The code uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and `d3.scaleOrdinal` with an interpolated rainbow color scheme, along with `transition.attrTween` for smooth updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bfdb9ba81ab4b8f866acca9f7137e75?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
