To graphically represent the relationships between several sets of information, one type of diagram is the Venn diagram, which uses overlapping circles. If the circles of two entities overlap, those entities share that quality; otherwise, they do not. A Venn diagram is useful for visually depicting the connections between and distinctions between multiple concepts. Because of this, Venn diagrams are a helpful tool for illustrating the connections between various ideas. Quickly show where two paths converge or diverge. In a Venn diagram, the central circle indicates a nexus or core idea that can be dissected into the surrounding circles, while the outer labels are more generic and less defined. Overlaps can also draw attention to how otherwise seemingly dissimilar contexts are quite similar. There are many ways to draw a Venn diagram, but the most common uses overlapping circles to represent the different nodes. To represent groups of ideas, concepts, numbers, or actual objects, we can use individual circles as a stand-in. The union or intersection of two sets in mathematics is the gathering of all elements shared by the overlapping or intersecting sets. When two sets do not share any elements, we say those elements constitute the “complement set” of those sets.
