This zoomable sunburst visualizes a hierarchical dataset representing the Flare visualization toolkit, using an SVG rendering with animated transitions powered by D3 v5. The visualization shows the hierarchical structure as a radial layout, with arcs partitioned by value and colored by top-level category. Clicking a node zooms in to expand that subtree, while clicking the center circle returns to the root. The code uses `d3.partition`, `d3.hierarchy`, `d3.arc`, and `transition.attrTween` to animate both the arcs and their labels, with data loaded from an Observable standard library module.
