Abstract
The art of computing Feynman integrals has always involved graph theory in the sense that the specific structure of each Feynman graph really matters. Feynman integration is very hard so quantum field theorists have become very skilled at extracting every bit of information they can from the structure of the graphs as well as having many more analytic tricks.
