Nature and the world of human technology are full of networks. People like to draw diagrams of networks: flow charts, electrical circuit diagrams, signal-flow graphs, Bayesian networks, Feynman diagrams and the like. Mathematically minded people know that in principle these diagrams fit into a common framework, namely category theory. But we are still far from a unified theory of networks. Here we explain how networks of various different kinds can be seen morphisms in various different categories, and show how these examples are connected by functors.
