Mitt Romney’s campaign put out a set of graphics illustrating a “gap” between what Obama promised and what he has delivered.  The graphic is in the form of a Venn diagram, a visual designed to show the overlap between two conditions.  For an example, see this platypus playing a keytar.

Unfortunately, Romney’s overlapping circles are not Venn diagrams, making the campaign somewhat ridiculous and giving nerdy liberals all over America a good chuckle.

So, there you have it, an example of how not to use Venn diagrams to illustrate your data.
