I could whip upa similar graph without breaking a sweat that says whatever I'd like, and it would have all the same hallmarks of this one. I could even do it in PHP using ImageMagick (if I felt masochistic) and fake the file header to say it was created using GD. Or build it in photoshop, and pull it into a binary editor.
So I think unless there's someone who can point to greater evidence that this is an internal graph, there's just no reason to believe it is.

The distribution this poll shows is not so outlandish as to be unbelievable, and importantly it does not lend itself to overwhelmingly support one side over the other. Why would anyone spend time and effort to fake it?
It's a heated argument on the internet. There'd be plenty of incentive to fake a graph in order to bolster one's opinion.
However, the design matches the defaults of google forms, exact colors and their sequence, too: http://imgur.com/WPC0ogZ
Also the header says "gd-jpeg v1.0", it’s a cross platform open source C library with bindings for all modern programming languages including Go and Python: https://en.wikipedia.org/wiki/GD_Graphics_Library
Even if that’s a fake, it’s a good one.
