Check if graphviz folder is set on your PATH variable. If not, you should add folder of gvpr.exe (usually %Graphviz_folder%/bin) to the PATH variable.
Dear Joao,Thank you for your help . After adding the bin to the path I get a done message in most cases but no one is created the only image created when my dir path points to the examples dir in your node module. I am trying to model angular 2 projects some times I get a can not read property forEa CV h of undefined. I never get a PNG. I guess this has some thing to do with dependency scrolling. Ariel

Can you try with the latest tsviz version? I tried running against that example (from here: https://github.com/johnpapa/angular2-tour-of-heroes) and it generates the diagram.
When I got this error it seemed that my installation path of Graphviz was wrong, fixed it with
ln -s /usr/bin/dot /usr/local/bin/dot
