what is the browser support for this

[landed1]

If you can add this to the docs that would be great..I don't see this being canvas but I would like to know how far back this works...

Hi @landed1! I didn't check all the browser versions, but technically all the browsers that support canvas should work: http://caniuse.com/#feat=canvas (doesn't work on IE8)
I'll add it into the README, thanks!

Edit : support IE10+, doesn't work on IE8 and IE9.

Thank you Vincent.
