Because of the well-known nature of Venn diagrams there are many questions that people may have about them that are not answered by the survey. Some of these questions are gathered here, and some answers provided.
ANSWER: Generally, we will grant permission for non-commercial usage of the diagrams. However, the diagram renderings found on this website are copyrighted, so permission must be obtained in advance by writing to the first author and, when used, proper attribution must be given.
ANSWER: Yes, and on all higher number of curves. See the page What is a Venn Diagram?.
ANSWER: There does not appear to be a mathematical term for the area of intersection in general - please send us email if you know one.
There is a symbol from Christian mysticism for the intersecting region of two circles as in the 2-Venn diagram; the name is `Viscera Pisces' and the region represents the intersection of the spheres of heaven and earth. The name (also spelled `vesica piscis') literally means "fish bladder" or "flesh of the fish" - if the edges of the intersecting region are extended beyond the ovoid shape, the lines form the early Christian fish symbol (as in this figure). The ovoid centre of the region is referred to as the `mandorla' (Latin for "almond").
ANSWER: This is a popular request; there are many answers.
