implementing Canvas to assure accessibility

Greetings, WebAIM:

I'm wondering if Steve F./others could offer the list an update on
Canvas accessibility. One of Steve's recent tweets, pasted below my
name, indicates progress.

What I'm hoping for is an update on the application of/implications
for the use of Canvas, with respect to accessibility, in the real
world, right now.

Questions that are crossing my mind include:

-- If Canvas is implemented to create an image, but the raw data is
still available, will that raw data suffice, in terms of
accessibility? I would think some kind of textual description would
be valuable to all, including anyone using an older browser that
might not support Canvas.

-- Are there any Canvas-generating libraries that are particularly
focusing on assuring accessibility?

-- What is the best source of accessible examples?

Thanks.
Best,
Jennifer
