+**Graph theory** is the study of [Graphs](/wiki/graph), mathematical structures used to model pairwise relations between objects. It explores networks of [Nodes](/wiki/node) (or vertices) connected by [Edges](/wiki/edge), revealing fundamental patterns in connectivity. This elegant field finds wide application, from optimizing routes and understanding social networks to the architecture of computer systems.
