You mean something like MathGL but for the GTK+/cairo stack ?

I can't think of anything off hand which exists that does that, and I
would see myself using it at one point or another.

I would suggest that you do this with cairo directly, and not have a
hard GTK+ dependency in your library, i.e. you could provide a GtkWidget
as a separate thing, but have the main library only depend on cairo,
this would allow one to plug it into a GTK+ application easily, but also
use it directly with cairo on a wide variety of cairo rendering backends
(can be interesting for directly rendering charts onto a PDF surface for
example).
