Graph Theory
Graph theory is the branch of mathematics dealing with graphs. In network analysis, graphs are used extensively to represent a network being analysed. The graph of a network captures only certain aspects of a network; those aspects related to its connectivity, or, in other words, its topology. This can be a useful representation and generalisation of a network because many network equations are invariant across networks with the same topology. This includes equations derived from Kirchhoff's laws and Tellegen's theorem.

“When producers want to know what the public wants, they graph it as curves. When they want to tell the public what to get, they say it in curves.”

“A theory if you hold it hard enough
And long enough gets rated as a creed....”
