This zoomable sunburst visualization displays the hierarchical structure of the Flare data set, using nested arcs to represent parent-child relationships and their relative sizes. Built with D3 v5, it renders the hierarchy as an interactive ring layout where users can click any arc to zoom into that subtree, with smooth animated transitions between views. The visualization uses `d3.partition`, `d3.hierarchy`, and `d3.arc` for geometry, while `transition.attrTween` and `transition.tween` handle the interpolated animation of arc paths and labels during zoom operations.
