In [[mathematics]], '''[[w:graph theory|graph theory]]''' is the study of [[w:graph (discrete mathematics)|graph]]s, which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of [[w:Vertex (graph theory)|vertices]], nodes, or points which are connected by edges, arcs, or lines.

* In [[Leonhard Euler|Euler]]’s investigation of the [[w:Seven Bridges of Königsberg|bridges of Königsberg]], he discovered that it was the general arrangement of features that was important, not their exact locations. This observation led to the creation of graph theory, one of the earliest incarnations of [[topology]].
