automata – Finite state machines, graphs and trees in METAPOST
The package offers a collection of macros for METAPOST to make easier to draw finite-state machines, automata, labelled graphs, etc. The user defines nodes, which may be isolated or arranged into matrices or trees; edges connect pairs of nodes through arbitrary paths. Parameters, that specify the shapes of nodes and the styles of edges, may be adjusted.
