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?

Did you try the CodeProject article series by Sukram:

Answer 2

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).

Take a look at my question: http://stackoverflow.com/questions/1710642/generate-dynamic-flow-chart
