This interactive sunburst visualization displays hierarchical data from the Flare dataset, animating radial arcs and labels when clicking to zoom into nodes. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render SVG paths, with `d3.interpolate` and `transition.attrTween` for smooth 750ms animations. The color scale uses `d3.scaleOrdinal` with `d3.interpolateRainbow`, and labels rotate and flip based on arc position. Data loads asynchronously via an Observable stdlib `require` call, while a central circle returns to the root view.
