[Vala] Graphic toolkits for Vala?

[CaStarCo <castarco gmail com>]

Hello,

the last days i was fighting with some linux diagram editors (such as dia,
umbrello, argouml...). And these programs don't cover my needs.

At the end i thought may be i could make a program to help me to create
beautiful diagrams.. but never i made a program that works with editable
graphic elements.

¿Whic libraries should i use? (Probably i'll program it with Vala)

I thought in clutter and/or cairo, but i don't know if these libraries do
that i think they do .

Thanks in advance
