Fork of D3 v5 Zoomable Sunburst
A zoomable sunburst chart visualizes the hierarchical structure of the Flare dataset, with arcs color-coded by top-level category and sized by value. Clicking a segment rotates and scales the visualization to focus on that subtree, using D3 v5 transitions and `transition.attrTween` to animate arc geometry and label positions. The chart renders with SVG, leveraging `d3.hierarchy`, `d3.partition`, and `d3.arc`, while loading data asynchronously via the Observable standard library and `require`.
