This interactive sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment sized by value. Clicking a node zooms in to reveal its children, while the central circle returns to the root view. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, `d3.arc`, and animated transitions via `transition.attrTween` to smoothly interpolate arc positions. Colors derive from a `d3.scaleOrdinal` over the rainbow palette, and labels rotate with their arcs.
