What is depicted in a 'Venn diagram'?

A Venn diagram is a visual tool used to illustrate the relationships between different sets or groups. It typically consists of overlapping circles, where each circle represents a set, and the areas where the circles overlap indicate the elements that are common to both sets. This graphic representation allows for a clear understanding of how the sets are related, showing not just their similarities but also what distinguishes them from one another.

Using a Venn diagram is particularly effective in various fields, including mathematics, logic, and even comparisons in literature or science, where one might want to highlight shared characteristics or differences among multiple subjects. This makes the choice particularly suitable for understanding concepts involving categorization and comparison.
