What diagram can represent set relationships visually?

A Venn Diagram also known as a Set diagram is the visual representation of set relationships. A rectangle acts as the boundary and encloses within, all the different sets visually represented as circles. The rectangle is the Universal set. The circles are different sets that fall in the same category. The curved lines that are formed by the spaces of the overlapping circles represent the elements/numbers that have properties common to all the circles that are overlapping.
