Comics with Venn diagrams.

These are not to be confused with Euler diagrams, as they are only a subset of Euler diagrams.

For Venn diagrams every possible intersections there could be must be shown. So for 2 circles there has to be one overlap zone, for 3 circles there must be four zones, one zone with all three circles overlapping and three zones with two circles overlapping.

In general for an n component Venn diagram there must be all 2n hypothetically possible zones, corresponding to some combination of inclusion or exclusion in each of the component sets.

An Euler diagram only needs to show the zones that have common objects, see for instance the Euler diagram in 1810: Chat Systems with 24 circle. This would have resulted in 224 (about 16,8 million) zones should it have been drawn as a Venn diagram, with almost all of them being empty.
