GTK+ Charts and Blueprint

[zeta <kmsiete gmail com>]

Hi there.

I want to start a library  for creating interactive and animated charts 
with gtk I am going to create a project on  github but before I want to 
know if is there any library for create something like that? and if 
someone can tell me some advise of how to start or what should I do.

Also I want to create a Blueprint app for easily create mockups for 
Gnome, and mobile systems, something like evolus-pencil.

Regards, to everyone.
