VCG

If the option -vcg is used, a representation compatible with the VCG 1.30 graph-visualization program is written to standard output, on the basis of the finite-state automaton read in from standard input. For example, if the file fig19.tnd consists of the transducer given in figure 19 of Roche and Schabes ([12]), then the following pipe produces the illustration given in figure 1.

% fsa -td fig19.tnd | fsa -vcg | xvcg -

Figure 1: The FSA Utilities program supports output for two external graph visualization programs. This figure illustrates the use of VCG. This example is the determinized version of an example given by Roche and Schabes (their figure 19).
