D3 v5 Zoomable Sunburst
This zoomable sunburst chart visualizes hierarchical data from a flare.csv file, showing the relative sizes of data tables and their parent-child relationships. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the radial layout as SVG paths. Clicking a segment triggers an animated transition that re-centers the view, using `d3.interpolate` and `transition.attrTween` to smoothly morph the arcs and labels over 750 milliseconds, with color encoding and opacity distinguishing hierarchy levels.
