{"version":"1.0","type":"rich","title":"D3 v5 Zoomable Sunburst","description":"This interactive visualization displays a zoomable sunburst chart representing the hierarchical file structure of the Flare data. Using D3 v5's `d3.hierarchy` and `d3.partition`, the code computes the radial layout and renders it as SVG, with arcs colored by top-level category. Clicking a node triggers a 750ms animated transition via `g.transition()`, interpolating the arc geometry with `transition.attrTween`. The visualization loads the dataset through `observablehq.Library` from the `@observablehq/flare` module, with labels and arcs fading based on visibility thresholds.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fce5f2939258451f91468f6df61b3b6e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
