Venn diagram

A Venn diagram is a visual tool that uses overlapping circles to show relationships between different sets or groups. Each circle represents a group with common features, and the overlapping areas indicate elements shared by those groups. Non-overlapping parts show elements unique to each group. This helps easily compare and understand how groups relate to each other, whether they have overlaps, are separate, or are completely contained within one another. Venn diagrams are useful for illustrating concepts such as commonalities and differences in data, ideas, or categories.
