D3 v5 Zoomable Sunburst
This zoomable sunburst chart visualizes hierarchical data from the flare dataset. Clicking a node zooms into that subtree, while a central circle returns to the parent level. The chart uses D3 v5’s `d3.partition` layout and `d3.hierarchy`, rendering arcs as SVG paths with `d3.arc`. Interactive transitions animate via `transition.attrTween`, updating arc geometry and label rotations with color scales from `d3.interpolateRainbow`.

Many thanks to Bryan Gingechen who answered my question about the necessary steps to get from an (Observable) JavaScript notebook to a vanilla JavaScript index.html. He presented his solution on blockbuilder.org
