{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This zoomable sunburst chart visualizes hierarchical data, displaying restaurant categories (fast food, pizza, Mexican, etc.) across multiple cities, with each arc segment representing a portion of the total. The visualization uses D3 v5's hierarchical layout and partition functions to compute the arc geometry, rendering the sunburst as SVG paths with animated transitions. Clicking on a segment zooms into that subtree, using `d3.interpolate` and `transition.attrTween` to smoothly animate the arc angles and radii. The data originates from the Observable `@observablehq/flare` dataset, loaded dynamically via the Observable standard library's `require` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/527f2a3523134192bcb173cf4ad32f11?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
