Fork of D3 v5 Zoomable Sunburst
This zoomable sunburst diagram visualizes the hierarchical Flare dataset, showing the relative sizes of categories and subcategories through nested arcs. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` to render the SVG, with an ordinal color scale based on `d3.interpolateRainbow`. Clicking a node triggers smooth animated transitions via `transition.attrTween` and `d3.interpolate`, rescaling arcs and labels to zoom into the selected branch. Labels rotate and reposition based on arc angles, and tooltips via `title` show full paths and numeric values.
