Plotly’s Scattergl trace moves point clouds to the GPU via WebGL, delivering 50 k+ points at interactive frame rates. This post shows the one‑line switch in JS and Python, the feature gaps you’ll inherit, and a practical benchmark you can run today.
Use go.Scattergl to keep Plotly responsive with tens of thousands of points, then verify static exports before shipping.
When Plotly’s scattergl shows blank points or sluggish zooming, the culprit is often WebGL buffer limits or inefficient updates. This diagnostic guide walks through symptom checks, fixes, and when to ask for help, ensuring a smooth 60 FPS interactive plot.
Plotly.js offers Scatter (SVG) and Scattergl (WebGL). This guide helps decide which to use for large point sets, comparing performance, memory, features, and providing a step‑by‑step validation plan.
Need to plot hundreds of thousands of points in Plotly? Learn why Scattergl outperforms Scatter, how to switch with a single line, and what features drop out. Practical example included.
Decide between Plotly's SVG scatter and WebGL scattergl traces: a compact comparison, the real trade-offs, a threshold-gated implementation, and how to validate with your own data.
Learn when and how to switch Plotly’s default SVG scatter trace to the WebGL‑accelerated scattergl type for smooth interaction with large datasets.
Plotly’s scattergl renderer lets you plot massive point clouds with minimal lag. This guide walks through prerequisites, setup, performance checks, and fallback strategies for older browsers or low‑end GPUs.
Plotly’s default scatter uses SVG DOM elements and slows down with tens of thousands of points. Switching to scattergl moves rendering to WebGL for interactive exploration of hundreds of thousands of points, with clear trade-offs in features and payload.
