Is it in beta? Doesn't seem to work now... and your link has no chart but an img placeholder in the page.

thanks! seems to work when requested directly, but not integrated / within HTML / jquery etc.

Hmm. That's something that I'll have to look into. It should be served the same as anything else.

try it with some sort of dynamic data, one you never http-request it before (talking about the page-embedded scenario). i can't get it to work, even in different environments/networks. it always works when the chart is requested directly :(
