This zoomable sunburst plot visualizes the hierarchical flare dataset, displaying nested categories as concentric arcs whose angular width and radial distance encode each node’s relative value. Clicking an inner arc zooms into that subtree, animating the layout and updating visible labels. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and draw the geometry, with `transition.attrTween` handling the smooth zoom animation. An ordinal color scale applies a rainbow palette to top-level branches, and SVG paths render the final graphic, which supports interactive navigation through the hierarchy.
