For correct functioning is necessary:
Install Graphviz ( http://graphviz.org/Download_windows.php)
Install WinGraphviz ( http://wingraphviz.sourceforge.net/wingraphviz/)
Import the reference to dll file at the project in Visual Studio (C:\Program Files (x86)\WinGraphviz\WinGraphviz.dll)
Add the using statement to the class for using the WinGraphviz components (using WINGRAPHVIZLib;).
