- These are comics that relate to Venn diagrams.
- They should not be confused with Euler diagrams although some of the comic that mention Venn diagrams actually shows Euler diagrams instead.
- If Venn diagrams are mentioned, even though it is an Euler diagram, not a Venn diagram, then they will still be included here.
- Randall seems to have made mistakes, or maybe done this on purpose as indicated with the comic 2721: Euler Diagrams.
- Apart from that comic where he mentions that he wishes to call all Euler diagrams for Venn diagrams he has also made the "mistake" two time before:
- A Venn diagram shows all possible combinations of two or more sets, including those with no elements, and therefore all of the circles must intersect.
- An Euler diagram need only depict the non-empty combinations, and therefore does not have this constraint.
- All Venn diagrams are also Euler diagrams, but not the other way around!
- Thus this category is a sub category of Euler diagrams.
- Only the three mistake comics should be included directly in both categories.
- 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. It thus has 25 = 32 zones.
