The aim of this package is to turn GAP more user-friendly. It requires the usage of external programs as is the case of graphviz, a software for drawing graphs developed at AT & T Labs. It is used not only to draw right Cayley graphs of finite semigroups and Schuzenberger graphs of finite inverse semigroups but also to visualize in the usual way the egg-box picture of a D-classe of a finite semigroup.
If the current version of sgpviz is not yet one the GAP packages you have installed please load the stable release from GitHub or from the GAP web page and follow the instructions there.
The development version is available from this GitHub repository, which you may find to be a good alternative.
