# Talk:Venn diagram

I drew these using jave.de and I'm aching for the same kind of graphical draw tool as found over at twiki, the twikidraw...I've raised the idea at the village pump... just finding a java person that knows enough about xml to write to the expat library in php...that's all ;) dennisdaniels

I just came looking for the answer to this question - are there sets of sets that cannot be represented by a 2D venn diagram? If so, how about if you extend the diagram to more than 2 dimensions? If somebody knows the answer, it should be included in the article, I think. -- Khendon 10:08 Sep 30, 2002 (UTC)

What's the difference between a Venn diagram and an Euler diagram? The article doesn't even hint at that. Both of the diagrams shown are Venn diagrams, as I have alwasy understood the term. Are they also both Euler diagrams? Michael Hardy 23:57 4 Jul 2003 (UTC)

They're pretty much the same, except for the name. Mathematicians felt sorry for John Venn, so they named it after him. It's in the article and external link. Poor Yorick 00:04 5 Jul 2003 (UTC)

The page could use some mathematical markup. Like: A is a proper subset of B is written as: A (a rotated U) B, someone know how to make those symbols? BL 19:04, 7 Sep 2003 (UTC)

I don't think it links to the right Mr. Edwards. T0pem0 11:30, 14 Apr 2004 (UTC)

I am in a Probability Theory class.. and today was like the 3rd day of class. We were talking about Venn Diagrams, and I swear I heard the professor say
"Those are venn diagrams and I encourage you to use them when you think about sex"

So I'm sitting in class, trying to figure out how Venn Diagrams can be applied to sex before I come to the realization that he said "SETS", not sex. Oh well, so much for math being frightfully interesting.
