A zoomable sunburst visualization displays the hierarchical flare dataset, showing nested categories as concentric arcs colored by top-level branch. Clicking an arc zooms to that node while the central circle resets the view. Built with D3 v5, the example uses `d3.partition` to compute layout, `d3.arc` for arc paths, `d3.interpolateRainbow` for color, and `transition.attrTween` plus `d3.interpolate` to animate arc geometry and label positions during zoom transitions. SVG elements render the visualization with interactive click handlers.
