{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This interactive sunburst chart displays the hierarchical Flare dataset, where each ring segment represents a node and its angular width encodes the node's value. Clicking a segment zooms into that subtree, smoothly animating the layout using D3 v5’s `d3.partition`, `d3.hierarchy`, and `d3.arc` with `transition.attrTween` for interpolated arc paths. Labels and fill opacity update dynamically, while a central circle returns the view to the root. The visualization is rendered as SVG and uses `d3.scaleOrdinal` with an interpolated rainbow palette.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/295c6275e11941128efd4e04b5a8aa33?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
