Euler-Venn charts are used to visualize sets and operations on them. The set is represented by a part of the plane bounded by a closed curve; the elements of the set are points (not necessarily all, as, for example, in the case of finite sets) of the plane inside the closed-loop. The original sets are often represented by circles. The only disadvantage of this method of images - you can not depict an empty set. Using Euler-Venn charts, we represent the union, intersection, difference, and symmetric difference of sets (the formed sets are denoted by hatching).
