This zoomable sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment representing a category or subcategory sized by value. Clicking any arc zooms into that node, smoothly animating the layout so the selected subtree expands to fill the view. The chart is built with D3 v5 using the `d3.partition` layout and custom `d3.arc` paths, rendered as SVG with transitions driven by `transition.attrTween` and `d3.interpolate`. Labels rotate and fade based on visibility thresholds, while a central circle resets the view to the root.
