This looks awesome, thanks for sharing - do you have any info on how it compares to matplotlib in terms of plotting speed? (even just rough estimates)

A quick inspection of the article suggests there's a difference of intent.

<snip> Datoviz is a relatively low-level visualization library. It focuses on rendering visual primitives like points, lines, images, and meshes — efficiently and interactively.

Unlike libraries such as Matplotlib, Datoviz does not provide high-level plotting functions like plt.plot(), plt.scatter(), or plt.imshow(). Its goal is not to replace plotting libraries, but to serve as a powerful rendering backend for scientific graphics. </snip>

Yes, although there isn't much to do to go from Datoviz to simple scientific plots like scatter plots or polylines with axes. It's just a few lines of code. I should probably clarify the documentation.

Good idea, I should do benchmarks on simple plots. It's orders of magnitude faster. Above 60 FPS on hundreds of thousands to even millions of points depending on the type of plot, on common hardware.

Thanks, I expected as much but wanted to confirm before I commit to learning something new, not for laziness but for prioritising what to learn next. Project looks great either way!

I ran a quick benchmark comparing Matplotlib and Datoviz on a simple interactive 2D scatter plot. In short, Datoviz is 20 to 2000 times faster.
