I wanted to try Bountify (https://bountify.co/) so I asked for a little thing to create charts. You give it a username, it pulls the last 100 submissions for that user, and charts what urls those subs are. Or you give it an url, and it pulls the last hundred subs of that url and creates a chart of the users posting it.
I put a $25 bounty on it. I decided before I posted it that I'd accept the first working answer. (My post was lousy. I could have included much better detail.)
This is what I got - pretty quickly.

I've put some examples on Imgur. Please note that these are just some examples picked pretty much at random. I'm not trying to make any point with this; they're just examples.
