# Category:Venn diagrams

Comics with Venn diagrams. Be not confused with Euler diagrams, Venn diagrams are much more restricted.

In a Venn diagram every possible intersection must be shown. In general for an n component Venn diagram there are 2^{n} hypothetically possible zones, corresponding to some combination of inclusion or exclusion in each of the component sets. A Venn diagram with 2 circles, see 668: Pandora, has 2^{2} = 4 zones; one overlap zone, two zones without overlap and one outside zone.

So far only Venn diagrams with two or three circles have been used in xkcd.
