What I love about xkcd is that you read it and think "what a crazy story, that can't possibly be true" and then look it up and it's basically true

But you can still have math on your axes:
ggplot(mtcars, aes(wt, mpg, label = rownames(mtcars))) +
geom_point() + theme_minimal() +
labs(x=expression('Concentration of'~CO[2]))
ggplot(mtcars, aes(wt, mpg, label = rownames(mtcars))) +
geom_point() + theme_minimal() +
labs(x=expression('Concentration of'~CO[2]))

Wonderful infographic on my paper showing that "flight" species of baleen whales generally call too deeply and quietly to be heard by hunting killer whales, unlike the "fight" club.

It's actually a very well written expose of predatory journals, published in one... brilliant work. Other than the hilarious name and address of the author, seems legit.
