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 2ⁿ 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 2² = 4 zones; one overlap zone, two zones without overlap and one outside zone.

2122: Size Venn Diagram is the first comic to include five components, previously only Venn diagrams with two or three circles have been used in xkcd.
