**gl‑histogram‑scatter** is a small WebGL library that builds image histograms using the “parallel scatter” technique described in AMD’s “Efficient Histogram Generation Using Scattering on GPUs.” It leverages `regl` and a vertex‑shader‑based scatter pass to compute histograms (and custom reduction operations) directly on the GPU, requiring only a modest number of vertex texture units. The package is aimed at web developers and graphics programmers who need fast, GPU‑accelerated histogram calculations for visualisation, analysis, or image‑processing tasks in browser‑based applications.
