Unfortunately, there is no good tutorial the Gnome Canvas with Gtkmm. 
However, you will easily find tutorials on the Gnome Canvas in C. You 
should have no problem porting the examples with Gnomecanvasmm . But be 
careful because the tutorials I read on the web are quite old, and 
therefore were written for the first API version of Gnome Canvas (we are 
now at 2.10). Nevertheless, the differences aren't heavy.

The Canvas object inherits from Gtk::Widget. Thus, you can add it to a 
container just like any widget. It is common to add the Canvas to a 
ScrolledWindow permitting to easily scroll through the Canvas.

I agree that the Gnomecanvasmm reference is poor. You should have a look 
at the Gnome Canvas  API  Reference instead.
