The feynmf package provides an interface to Metafont (inspired by the facilities of mfpic) to use simple structure specifications to produce relatively complex diagrams. (The feynmp package, also part of this bundle, uses MetaPost in the same way.)

While the package was designed for Feynman diagrams, it could in principle be used for diagrams in graph and similar theories, where the structure is semi-algorithmically determined.
