D3 v5 Zoomable Sunburst
This zoomable sunburst visualization displays a hierarchical dataset of the Flare software project, with each arc segment representing a category or leaf node whose angular width encodes its relative value. Clicking a segment transitions the view to center on that branch while shrinking others, enabling navigation through multiple levels of the tree. The visualization is rendered as SVG using D3 v5’s `d3.partition` layout, `d3.arc` for path generation, and D3 transitions for smooth zooming animations. Data is provided as an inline JSON object.
