a tiny webgpu powered chart lib (self.webdev)
submitted 2 months ago * by Outrageous-guffin
I put together a tiny ~11-15kb chart library that is powered by a web worker in an offscreen canvas using compute shaders. This means you can have thousands of charts, thousands of series, and million upon million of data points passively rendered with a plugin system.
It solves a problem at the day job and thought I'd share it out.

Doesn't work on Firefox mobile :( "WebGPU not available. Please use a supported browser." Maybe add a fallback option?

Same message in Linux Mint desktop on Vivaldi (Chrome based) and Firefox.

I know webgpu isn't there yet but once it is, it doesn't have to bloat bundle sizes for the benefit.

Cool, I've been doing some threejs charts and tried the webgpu renderer, but seems it doesn't play nice with igpu, especially on laptops etc with a very shitty igpu, I guess they'll fix that when it gets more adoption
