What Hacker News says
2 sourcesa few reasons.
the main one is that i know canvas and can implement everything i need, but would need to learn a lot of webgl to get any further than a basic PoC.
browsers limit how many webgl contexts you can acquire. chrome is capped at 16, so if you need more than 16 charts on a page, you're out of luck.
initializing webgl is actually slower than canvas 2d.
it's difficult to draw lines of different thicknesses in raw webgl - it takes a lot of code.
there are projects which abstract webgl nicely to provide canvas-like ergonomics, like Two.js, Pixi.js, or Canvas2DtoWebGL/litegl [1], but they would make the codebase much larger and more complex.
