How much actual WebGL vs. SVG development have you done? How many devices have you tested?
You obviously have experience in this area that is great to share in a way people can learn from. But first it's necessary to be civil, as all users need to be here.
First of all, that's a pretty condescending thing to say and you're obviously not speaking for everyone. I wouldn't mention that if you weren't tone-policing me.
I'm telling you that if you make technical decisions based on "feature support" charts, you're going to fall flat on your face with WebGL. That's pretty useful information unless you never have to do any actual work with that technology, but then your opinion is also irrelevant.
> Knee-jerk disagreeing and suspecting everyone to have less experience than you will just get you downvoted everywhere.
Nobody who has experience with WebGL and SVG will say WebGL is better supported across the board. You'll have to take that at face value, there's no scientific study for it and I'm not going to just give out more information than I'm comfortable with.
I'm getting downvoted across the board here, presumably for using "bad" words like "terrible" to describe everyone's favorite Web technology they never really used. Or if they have used it, they don't know how poorly it compares to something "evil" like Flash. People want "the good guys" to win, which means "free and open source" and "standard". It makes them upset when somebody criticizes that harshly, but it's the reality.
I got some upvotes initially, by the way. Not that I care either way, I'm not paid in upvotes.
This statement isn't even vaguely true. SVG support is quite incomplete and inconsistent across all browsers (both desktop and mobile), while Webgl has been comparatively well supported on mobile for many years (Android 4.4 lacked support; Android 9 is now out).
The only issues you might have with most common webgl applications on mobile is performance & battery drain but that's equally true of SVG.
