When I think of practical uses for a venn diagram I think of writing labels in each distinct section... this doesn't seem very practical in that regard. What would be really cool (and practical) is if all the different segments / sections were of relatively similar sizes. Anyone know if there's a way to draw that? The examples shown in the article have really large areas and really small areas... EDIT: It seems venn diagrams lose their "functionality" after 5 sets. After that they are far too complicated.
