NOTE: I'm not entirely certain about the origin of this graph, so I apologize if my citation isn't correct. The earliest version I could find was on imgur from user r/skeptic (yes, associated with the Skeptic subreddit).
I think the illustration above is a good way of a) demonstrating that correlation does not equal causation and b) sticking it to anti-vaxers who use a lot of correlational data (see below) to back up their theories about why rates of Autism have been increasing.

The one thing that throws off the theory is the lack of correlation between autism and race/SES. Which I am pretty sure organic produce is mostly consumed by the higher SES white group at a much higher rate.
