This interactive sunburst chart visualizes the hierarchical structure of the Flare dataset, which contains software package classes and their sizes. The visualization uses a zoomable and navigable radial layout where users can click on any node to re-center the view and explore nested categories. The chart is rendered as SVG using D3 v5, with the partition layout computed via `d3.partition` and `d3.hierarchy`. Interactive transitions employ `transition.attrTween` and `d3.interpolate` to smoothly animate the arc geometry and label rotations during zooming.
