Yeah, I was hung up on that as well. Obviously no reflection on the product/code/whatever, but when you go with "sounds like", try to pick a word that can only be pronounced one possible way.
Day-a-tee sounds about right - but I'm not precious. It was a deliberate miss-spelling of "pie" with some other letters added on... and quite possibly a mistake.
Very interesting, but most of these examples look like they would be fairly nonsensical to someone without JavaScript enabled (especially the line chart). To say nothing of those who use screen readers.
Is there a handy way of providing some more meaningful 'alt' text? Perhaps just ignore text in the element? (I didn't check -- you may already be doing this, but I didn't see it mentioned).
I used these in a small mockup app a little while ago. I'm aware of their inappropriateness for representing data, but for adding quick color, pop and smartness to a prototype, they performed beautifully.
Wow, awesome! I was going to roll my own (pie charts) this weekend, but now I don't have to (probably wouldn't have been able to, anyway). This looks great, thanks!
Since you only support IE9+, I don't see how any serious project would pick your charts. IE8 is still #3 most common browser version in the world. IE7 is #5.
Just checked my analytics out of interest. Sample of 200k unique visitors to a non-tech related website, 6.7% IE8 or less.
I would certainly consider using this tool even without knowing about the flash shim, especially for something that something is probably an eye-candy extra and not the central feature of a statistical page.
