Research direction
Review the existing crosshair implementation in VChart, likely in packages/vchart/src/component/crosshair. Examine how radar chart polygons are rendered (maybe packages/vchart/src/chart/radar). Identify the intersection logic needed to highlight polygon edges. Check any linked PRs or comments for design decisions.
