{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This interactive visualization presents a zoomable sunburst chart of the Flare data hierarchy, where clicking a ring segment smoothly transitions the view to that level. The chart encodes hierarchical relationships as concentric rings, with arc length proportional to values and colors assigned by top-level category. Built with D3 v5, it uses the `d3.partition()` layout, `d3.arc()` for path geometry, and CSS transitions driven by `transition.attrTween` to animate changes. The example loads data from the `@observablehq/flare` package and renders everything as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7babe7cceb394cd1bc93157a29f8c161?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
