Claude generates 500 canvas visualizations with zero libraries, vanilla JS only
mhmazur · x · 2026-10-06
mhmazur asked Claude Opus 5.5 to generate 500 visualizations using only the HTML <canvas> element—and it delivered, with Claude Code writing every one in vanilla JavaScript and a 2D canvas: no Three.js, WebGL, or libraries at all, including a recreation of archival bubble-chamber particle collision footage. Amusingly, Opus helpfully linked the source in every demo—it was just minified JavaScript nobody was going to read.
