That page says:

For drawing flow charts and the like, I would recommend using goocanvas,
this will let you use a variety of objects (shapes, lines, etc) and give
you some features like zoom, you can place objects in a virtual
coordinate space. You can also implement your own objects of course, and
all drawing is done with cairo.

goocanvas gives you a GtkWidget which can be placed in a scrolled window
or such in your application.

Cheers,
