WPF Graphing / Charting control

I want to produce an interactive chart - so far I've found GraphSharp which looked very promising, however I've found myself struggling due to lack of documentation and a difficult to understand sample.

All I need is to be able to place arbitrary WPF controls as my "nodes", have arrows joining them and be able to collapse / expand parts of the tree (users dont need to be able to move controls or anything like that).

None of the above strikes me as particularly complex (especially not in WPF), and I don't need anything fancy, however I'm aware that getting this bug free and behaving nicely could still end up take me a fair amount of time.

Is there a WPF layout control / library which can help me out with this, or am I bet开发者_开发知识库ter off creating my own?

Take a look into the WPF Controlkit by Microsoft - you can find on CodePlex.

Have you looked at the Telerik controls (not free)? The free Silverlight Toolkit on Codeplex doesn't suit your needs?
