{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This example shows a zoomable sunburst visualization of the hierarchical flare dataset, where clicking a ring zooms into that subtree and clicking the center returns to the root. The code uses D3 v5’s `d3.partition` and `d3.arc` to compute and draw the arcs, with `d3.interpolateRainbow` for color mapping and `transition.attrTween` for smooth animated zooms. Labels rotate and fade based on visibility criteria, and the data is loaded via the Observable `@observablehq/flare` package with the page rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9046ab1c729a424093c846e0159e02d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
