Charting a million points without freezing the browser
SVG charts have a lot to love, but with enough data the browser gives up. In this session, we'll climb the performance ladder step by step: canvas rendering, smart downsampling, workers with OffscreenCanvas, and finally the GPU with WebGL and WebGPU, all while keeping interactivity working. With practical examples in React, you'll learn to scale the D3 skills you already have to dense datasets rendering at 60fps.
