PhotonWebGL2 charts that don't flinch

40+ chart types across 2D, 3D, polar, finance, statistics, ML and model architecture. Millions of points at 60fps. Zero runtime dependencies.

Live gallery

Fast by construction

Geometry lives on the GPU (instanced WebGL2 + min/max decimation, on-GPU above 200k points). Axes and labels are drawn on a Canvas2D overlay, so text stays crisp at any zoom.

One context, many charts

Every plot renders into a single shared WebGL2 context and blits the result. A dashboard can hold dozens of live charts without exhausting the browser's context limit.

Scientific, not decorative

Linear, log, time, categorical and gap-collapsing session scales. Colorbars, error bars, contours, isosurfaces, volume raymarching, PSDs and regression bands.

Model architecture

Draw a PyTorch, Keras, scikit-learn or ONNX model — a Netron-style DAG in 2D, or cuboids sized by each layer's output tensor in 3D.

Any framework, or none

A zero-dependency core with React, Vue, Svelte, Solid and Gea bindings, plus framework-free Web Components — and a Python bridge for Jupyter and Colab.

Honest colour

12 perceptual colormaps (sequential, diverging, cyclic) and colour-vision-safe palettes. Value-mapped layers draw their own colorbar; register your own ramp by name.
