No worries!

It was not a explicit question where its easy to point at like a question mark (?) but I'd find any comment on a forum like environment to be trying to contribute to a discussion as a whole, where we can all share thoughts and counter thoughts constructively.

Anywhoo, XY seems like a cool lib. If you can find the usecase where you actually can leverage the power you should! Good job on Reflex.

I’m not trying to justify whether I'd personally use it, I was simply raising the question because the tradeoffs are interesting, and the replies, including Evidlo’s, have already taught me something.

I tried the library before commenting, it’s a cool project. The performance improvements at larger scales I've found are real. I was mainly just trying to have a conversation to learn where we all learn!

“Just move on” seems like a curious response on a discussion forum, though :)

I’m not convinced GPU acceleration is a meaningful advantage for most charting use cases. Most dashboards don’t render enough data for it to matter. Once a chart is dense enough for rendering to become the bottleneck, it normally is already be too crowded to be meaningful. Zooming can justify supporting larger datasets, but sampling/viewport culling and level of detail often avoid drawing unnecessary points...
