graphViz

[twistedmove]

I am not very familiar with graphViz, I downloaded using homebrew and changed the config.txt
PMTKgvizPath /usr/local/Cellar/graphviz/2.38.0/bin

and rerun the initPmtk3.m, but I still have this error when I run visualizeAlarmNetwork in demos/ and other functions which need graphViz
