Free or Open Source Diagramming Component for WinForms

Question

I need to be able to generate dependency diagrams programmatically. I'd like it to be able to generate a bunch of boxes with labels and connectors linking them, and ideally the component would position them automatically onto a design surface which could then be manually rearranged.

I'm using WinForms and C# 2.0 (VS2005).

EDIT: However, since it'll be an internal tool, I can probably use 3.5 SP1 and WPF if there any suggestions in that arena.

Must be free or open source.

Any recommendations?

You might want to take a look at GraphViz which is being distributed under CPL (i.e. free of charge). It is not exactly for .NET/WinForms but can be useful anyway. The library's main purpose is to visualize graphs (and dependency diagram is effectively a [directional] graph). You can use it to either get an image (graph layout) or an array of points (coordinates for you items).
