+A graph is a fundamental mathematical structure, a collection of points (vertices) and lines (edges) connecting some of them. It models relationships, from [Social Networks](/wiki/Social_Networks) to computational paths, illustrating connections and dependencies within [Data Structures](/wiki/Data_Structures). Graphs are powerful tools for understanding complex systems.
