Canvas for a gtk3mm application

[g4hx <g4hx gmx de>]

Hello everyone,

I need to write an application that is used to analyze network traffic.
To this end, I need a widget to draw a graph and display some relevant
data. As the subject suggests, I would prefer something like a canvas: I
would like to have some menus attached to the edges and nodes, which pop
up when the mouse enters. I would also like to zoom in and pan around. I
did not find any canvas class in gtk3mm, so I tried GooCanvas.
Unfortunately, the C++ bindings seem to be rudimentary at best, there is
also only one page of documentation.
For this project I would also like to have as few extra dependencies as
possible and any library should ideally be shipped with the popular
distributions.
I would much appreciate any help with this.
