The “When Can I Use” Web Widget

A script from Andi Smith that injects a chart of browser support with live data from Can I Use... I really like the idea of using it on any web tech blog post - so the information about feature support stays up to date over time. I think I'll be incorporating it into this site when I get a chance.

Alexis Deveria is cool with it.

It hits a JSON file at through YQL for the data. I wonder if there is a good way to cache it locally (localStorage?) so GitHub doesn't get used like a CDN so much. Or if YQL kinda already does that? Or if we could get it on some true CDN that is happy to get hammered with requests for it. CDNJS?
