computeHeatmapBins()
function computeHeatmapBins<T>(layer, dimensions): HeatmapBin[];Defined in: packages/core/src/heatmap/bins.ts:25
Divides the pitch into a binsX x binsY grid (in provider coordinates)
and buckets each datum by point count, or by summed weight if the layer
provides one. Pure — knows nothing about pixels/canvas/color, which keeps
it independently testable and reusable regardless of render backend,
mirroring computePitchGeometry.
Points outside the pitch extent are ignored rather than clamped into an edge bin — they're not part of the pitch's heat distribution. Points exactly on the far edge (x === length or y === width) land in the last bin rather than being dropped.
