The amazing pizzachart
From YouGov (who seem to already be regretting it).
This obviously isn’t a pie chart, because the pieces are the same size but the numbers are different. It’s not really a graph at all; it’s an idiosyncratically organised, illustrated table. It gets worse, though. The pizza picture itself isn’t doing any productive work in this graphic: the only information it conveys is misleading. There’s a clear impression given that particular ingredients go together, when that’s not how the questions were asked. And as the footnote says, there are a lot of popular ingredients that didn’t even make it on to the graphic.

Um, yes it’s not a graph. It’s a picture of a pizza.
And yes it is adding productive value, it’s a much more entertaining depiction of common pizza toppings than other ways of presenting the data, those which only a statistician would bother even glancing at.
I do have one big issue with it though. Everyone knows pizzas are cut into 8 not 6.

But cutting it into 8 would have required showing prawns, which would have been confusing since they weren’t a popular response
(at least if I’m right about the source)
