+xdot.py is an interactive viewer for graphs written in Graphviz's dot
+language. It uses internally the Graphviz's xdot output format as an 
+intermediate format, and PyGTK and Cairo for rendering.
+xdot.py can be used either as a standalone application from command 
+line, or as a library embedded in your python application.
