A Venn diagram is a widely used diagram style that shows the logical relation between sets. It is an illustration that uses circles or other shapes to show the relationships among things or finite groups of things. The diagrams are used to teach elementary set theory and to illustrate simple set relationships in probability, logic, statistics, linguistics, and computer science. A Venn diagram uses simple closed curves drawn on a plane to represent sets, and these curves are often circles or ellipses. The diagram shows all possible logical relations between a finite collection of different sets, with elements depicted as points in the plane and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. The interior of the circle symbolically represents the elements of the set, while the exterior represents elements that are not members of the set. Venn diagrams are useful for illustrating how different concepts or factors intersect with one another, and they can show at a glance how things are similar or different and where and how they overlap. They are used to think through and depict how items relate to each other within a particular “universe” or segment. Venn diagrams are widely used in mathematics, statistics, logic, teaching, linguistics, computer science, and business. They are a powerful tool for comparison and can also help you find correlations and commonalities that werent immediately apparent.
