Graph theory is a field of mathematics about graphs. A graph is an abstract [disambiguation needed] representation of: a number of points that are connected by lines. Each point is usually called a vertex (more than one are called vertices ), and the lines are called edges. Graphs are a tool for modelling relationships.

In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L(G) that represents the adjacencies between edges of G. L(G) is constructed in the following way: for each edge in G, make a vertex in L(G); for every two edges in G that have a vertex in common, make an edge between their corresponding vertices in L(G).
