I really like Github's impact graph about my Open Source project.

I would like to include it in a presentation, so I would like to download it as an image.

QUESTION: How to export this graph to an image?

Anything smarter than taking hundreds of screenshots and assembling them? That's the lame method I used last year to produce the image below (out-of-date):

If you don't need the textual labels (which are drawn as <p> overlays), you could just right-click the graph in Firefox and choose "Save Image As..." (It's a <canvas> element and Chrome doesn't yet offer a save option for those).

If you do need the date labels, I'd suggest looking for a Firefox screenshot extension capable of grabbing a complete screenshot of a scrolling sub-element in one go. (I know they exist for <iframe> elements, so being able to do it for a scrolled <div> isn't outside the realm of possibility)

Wonderful! Exactly what I needed. Strange "Save as Image" did not show on Chrome. – Nicolas Raoul Nov 28 '11 at 1:25
"Save As Image" doesn't show on Chrome because <canvas> isn't <img> and it takes extra code (which they may not yet have written) to generate a PNG from a raw grid of pixel data rather than pulling an already existing one from the cache. – ssokolow Nov 28 '11 at 7:47
