Venn diagrams

Venn diagrams are visual tools used to show relationships between different groups or sets. They consist of overlapping circles, each representing a set, with the overlap showing common elements shared between those sets. The areas covered by each circle illustrate the members of each set, while intersections reveal shared members. Venn diagrams help to easily compare, contrast, and analyze how groups relate to each other in terms of similarities and differences, making complex relationships more understandable at a glance.
