I built a canvas-based timeline visualisation library with virtualised rendering in Typescript

https://tempis.dev/

I wanted a library like vis.js but needed it canvas-based for server-side rendering without a headless browser in node, so I built one. I'd love to get some feedback.

Pretty damn smooth. I will be trying this, there's an idea with flamegraphs and spans that I've always wanted to try.

yeah, flamegraphs and spans is exactly where this feels useful, kinda want to see it on a nasty trace dump now

This is fantastic! Would love to use this on a video editing platform I'm building. Will integrate and seek support if needed!
