feat: TileGrid — interactive hover-to-highlight tile clusters#256
Merged
Conversation
SVG grid where each cell belongs to a cluster. On hover, all cells
NOT in the hovered cluster get greyed out (opacity 0.08), visually
isolating the cluster. Shows cluster ID and cell count.
Props: cols, rows, cellSize (default 12), cells (array of
{cluster, color}), bgImage (optional), gap (default 1).
Added to KNOWN_COMPONENTS and viewer registry.
One onMouseMove on the <svg> with coordinate→cell math replaces N per-rect onMouseEnter/onMouseLeave callbacks — O(1) listeners for any grid size. Matters for large grids (100×100 = 10K rects).
