Fork of D3 v5 Zoomable Sunburst
This interactive zoomable sunburst chart visualizes the hierarchical structure of the Flare dataset, representing files and their sizes as concentric arcs. Built with D3 v5, it uses `d3.partition`, `d3.arc`, and `d3.hierarchy` to lay out the radial tree, with animation handled by `transition.attrTween` for smooth zooming on click. The visualization is rendered as SVG, with fill-opacity and label visibility responding to the current zoom level, and colors assigned via `d3.scaleOrdinal` with an interpolated rainbow palette.
