Breakthrough In Drawing Complex Venn Diagrams: Goes to 11

Venn diagrams do not show proportion (what I assume you mean by amounts)!

If you draw a Venn diagram with a tiny little overlap, or a huge overlap, in order to make some point, [b]you are doing it wrong[/b].

Now it's one thing to do this for comedic effect, but I see this all the time when people are trying to be serious and it makes me stabby.

Venn diagrams are a way of visualizing overlaps in sets; the ONLY thing that matters is what region an element is placed, not how big that region is.

A Venn diagram is a precise tool which displays particular information with no ambiguity, and trying to shoehorn proportions into it just makes it muddy. Plus, humans are fucking terrible at telling how much larger one roughly circular area is than another; make those areas slightly different shapes, and it's even less helpful.
