It may be true (as in it may be satire), but this site’s fact check is a bit lame. Basically just “trust us, it’s fake”.
It’s an insubstantial article, but it is the exact same graphic. Everything’s identical except for the legend, date, and color scale, even the spacing of the legend.

A very quick flick through image results shows the EU Referendum map is taken straight from the BBC.
(Edit: I can’t say I’m not disappointed that Snopes didn’t do a better job, since this took me less that five minutes on mobile.)

Nuclear exposure causes a liking for anime titties got it.
Yes!!!
IT MAY, HOWEVER, BE A MISTAKE TO JUMP TO CONCLUSIONS
Reminds me of r/peopleliveincities, or that one time a 5G hater showed me a map of 5G towers, then a map of people getting sick of some disease or other. They matched!
The correlation assumes that intelligence was involved

Those damn cows
