WebGraph theory is a branch of mathematics concerned about how networks can be encoded, and their properties measured. 1. Basic Graph Definition A graph is a symbolic representation of a network and its connectivity. It implies an abstraction of reality so that it can be simplified as a set of linked nodes.
