Graph

A graph is a visual way to represent relationships or connections between items. It consists of points called nodes (or vertices) that represent entities, and lines called edges that show the relationships or interactions between those entities. Graphs are used in many fields, such as social networks to show friendships, maps to display routes, or computer networks to illustrate connections. They help us analyze complex systems by making patterns, clusters, or pathways easier to see and understand. In essence, a graph maps out how things are linked, providing a clear picture of their structure and relationships.
