D3.v4 Sunburst chart with line focus on over
A D3.v4 sunburst chart displays hierarchical data as concentric arcs, with each segment’s size proportional to its value. On mouseover, the chart highlights the hovered node’s boundaries by extending dashed black lines outward from the arc’s start and end angles beyond the outer radius, then hides them on mouseout. The visualization uses `d3.partition`, `d3.arc`, linear and square-root scales, and the ordinal color scheme `d3.schemeCategory20`, rendering to SVG with the flare dataset. Interaction events bind via `.on('mouseover')` and `.on('mouseout')` to toggle line visibility.
