BinTransform

BinTransform = object

Defined in: spec/transform.ts:25

Binning is declared, never pre-applied.

A frame that already carries buckets cannot be re-fitted: an eighty-column terminal, a 1200 px canvas and an eight-cell sparkline each want a different bucket count. Carrying the raw values plus this intent lets each renderer choose.
