How can I find python facebook graph api connection_name?

I am using python facebook graph api and after obtaining my access_token, I do the following:

graph = facebook.GraphAPI(response['access_token']) user = graph.get_object("me") 

Then I tried to call:

graph.get_connections(self, id, connection_name, **args) 

but I have no idea where to find connection_name and in the library example, I can only find "friends" used to get a list of your friend name.
