To clear up all the confusion, I offer the following copy and paste
from Wikipedia:

"Venn diagrams or set diagrams are diagrams that show all
hypothetically possible logical relations between a finite collection
of sets (aggregation of things). Venn diagrams were conceived around
1880 by John Venn. They are used to teach elementary set theory, as
well as illustrate simple set relationships in probability, logic,
statistics, linguistics and computer science (see logical
connectives)."

I think that explains things perfectly and simply and should serve to
end all further argument.

Ha, ha, very ironic! The first sentence is complete crap. They
show the 'inclusion' type relationships only.

It's a bad description, anyway. They are the overlapping circles
(or other shapes) that are often used to illustrate set membership.
The area in circle A but not in B represents the elements that
have propert A but not property B, and the area in the overlap
represents the ones that have both properties. And so on.

Nick Maclaren.

Laughing continues. Now I await someone who will explain the
explanation! This could really get interesting (though totally
off-topic; the definition of "on-topic" being the bit in the middle
which indicates the overlap between A, B and (of course) C).

Though I do wonder what the diagram would do if we introduced a
property "D". No need to answer that question - it's rhetorical
(assuming that's the word I'm thinking of). Work that one out ;-))
