charts on gtk+

[zeta <kmsiete gmail com>]

Hi there

I am new on the community, I am a bachelor student at BUAP, I love gome 
since I meet it, and know I want to contribute in something, I was 
writing an application with gtk and when I want to create some cool 
charts I see that there isn't a library for do it, or I don't find one 
that has native integration with gtk, so I decide to write one, but 
first I want to know If anyone is doing one, or if someone can guide me 
where to start, I think that I should do with the gtk draw area widget 
and cairo, but I'm not sure.

Regards

Miguel Angel
