Graphic visual diagram

I am trying to draw graphs (trees) and I am looking for algorithms to plot the graph. Is there a library for this in c / C ++ / objective-c? Otherwise, can anyone point out a good resource for this, preferably on the Internet?

Nodes can have different sizes.

There are quite a few layout algorithms for graphs in the igraph library , although you may also find it "too complicated." It is written in C, so you can embed it in C, C ++, or Objective C applications.

There is also GDToolkit (a set of graphic drawings)

But he does not have a free license, as I see now :(
