"You need to move your rectangles around a bit to get a 4-set Venn diagram, like if you scroll down a bit at http://math.gmu.edu/~eobrien/Venn4.html to find the rectangle-based option. A nice five-set drawing is at…"

"The fact that you couldn't quite get it to work for more than 3 elements (and the nature of the issue in getting it to work) gave me the feeling that it might be related to the 4-color theorem...It was strange. The thought just jumped into my…"

"The empty set is here but can't be seen :-) (intersection of none, part of outside) I think that nested sets are not convenient because it became quickly messy. My representation does not give the feeling that "{A,B}'" is…"

"I honestly wasn't sure what to do with the null set. In fact, I wasn't even sure if what I was proposing was exactly what you were looking for. I was trying to draw a venn diagram that represented each element of the power set of a set. So…"

"I think so, but I haven't tried it out for anything more than a set of 3 elements. But the procedure should go something like this: Write each element of the set down. Draw a circle around each element. Draw a circle around every possible…"
