A zoomable sunburst visualizes the hierarchical Flare dataset, where clicking a node zooms the radial layout to focus on that subtree, recentering and rescaling arcs with animated transitions. Rendered as SVG, it uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute the layout, with colors assigned via `d3.scaleOrdinal` and `d3.interpolateRainbow`. Interactive updates rely on `transition.attrTween` to interpolate arc geometry and label positions over 750 milliseconds.
