[Vala] Graphing with libdazzle

[Steven Oliver <oliver steven gmail com>]

Has anyone on here ever used libdazzle [1]? It looks really nice and
it appears to be fairly easy to use to make graphs for my project.
Appearances are deceiving though, and trying to convert the single
JavaScript example [2] in the repository to something I can do in Vala
has proved to be beyond my meager capability. There is documentation
for it on valadoc [3] but, sadly, as is typical for valadoc, it's a
lot of function and property listings with no explanations or
examples.

The only other example of usage I could find, was that I dumbly
stumbled onto a commit [4] for GNOME System Monitor which is in C.
That also proved unfruitful for me.

Any tips or examples would great!
