Yes, it uses the libgtkmmdraw that was announced on gtk-list recently. Jon
had some concerns about the speed of a Tk-like canvas for some of the
things he wanted to do - the overhead of the objects might be too much. 
I'm sure he can explain it better. More importantly we hadn't decided to
do Gnome-- at the time so it wasn't an option.

What do you mean by the Chart/Graph component editing the spreadsheet?

I will have to look at the Canvas in more detail, and think about how a
C++ wrapper would look. Is it possible to put the Canvas in "raw mode" and
just draw on it directly?
