Hi Ahmed,
Yes, sounds like it's time to update that wiki page and add an example
app for the graph module. Sorry for the confusion but with only a
small number of developers the docs tend to lag behind the code
sometimes :-)
I've modified your code and it runs successfully here. Please try it
now and see if it works for you.
