Show HN: A JavaScript library for data visualization in both SVG and Canvas

> DOM-like event bubbling

This does sound very interesting. I started playing with https://two.js.org/ for a browser game but the event system proved a challange. The typescript focus also looks promising. Will give it a try.

The readme needs some SVGs (you can embed graphics on github's readme)

edit: actually the web page too https://ripl-alpha.vercel.app/ - if your project render things to the screen, I want to see it!

Its not (just) the phrasing, its that you’re asking a loaded question the author already addressed in the OP. Your question is loaded because it presumes years of development means anything, and the author already wrote in the OP “im aware there are other libraries, but…”

Hey there,

If a focus is on performance, would you consider doing a side-by-side with other similar libs?

This benchmark was posted on HN a few years back, for example: https://benchmarks.slaylines.io/ (from https://news.ycombinator.com/item?id=23083730)

Or something like the bunnymarks for Pixi (https://www.goodboydigital.com/pixijs/bunnymark/) and Konva (https://konvajs.org/docs/sandbox/Jumping_Bunnies.html)

Your charts examples are kinda hard to compare with because the animations are so slow (not the fault of the lib, they're just slowly drawn to show the animations, I know, but it makes comparisons difficult.)

----------

In general, your lib reminds me a lot of Konva. I found their examples page to be really helpful in illustrating higher-level usage: https://konvajs.org/docs/sandbox/index.html

Maybe real-world use cases like that could be helpful for yours too? As it is, the readme doesn't make it super clear why it's preferable to any of the other existing libs yet. There are already so many, each with strengths and weaknesses... what sets yours apart?

For example, I don't know why "rendering to both Canvas and SVG" is a selling point in particular. Are there platform-specific reasons (native?) to prefer one over the other, as opposed to whatever a particular lib's implementation might be? Is there a use case where mixing and matching the two might be helpful?
