{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"A zoomable sunburst diagram displays hierarchical data from the Observable Flare dataset, with each ring segment representing a node and its value. Clicking a segment smoothly zooms and scales the visualization to focus on that subtree, using D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc`. Animated transitions via `transition.attrTween` and `d3.interpolate` update arc paths and labels, while `d3.scaleOrdinal` with an interpolated rainbow palette colors top-level branches.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2e4ee1d47760471e93b9f3ed16515321?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
