Euler diagrams

Euler diagrams are visual tools used to represent relationships between different sets or groups. They use circles or shapes to show how collections overlap or are distinct. For example, a circle might represent all students, and a smaller circle within it could represent students who play sports. Overlapping areas show common members, like students who both play sports and participate in music. These diagrams help clarify complex relationships, making it easier to understand intersections, subset relations, and differences among groups at a glance. They are widely used in logic, mathematics, and data analysis for visualizing set interactions.
