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?
Here is some references which might be interesting for you:
Diagrams.NET
Diagram.NET is a free open-source diagramming tools written entirely in C#. Put Diagram.NET WinForm Control into your form and, like Microsoft Visio®, the user can draw shapes and links. With some code you can control, change, add and delete these elements.
Microsoft Chart Controls
The samples environment for Microsoft Chart Controls for .NET Framework contains over 200 samples for both ASP.NET and Windows Forms. The samples cover every major feature in Chart Controls for .NET Framework. They enable you to see the Chart controls in action as well as use the code as templates for your own web and windows applications.
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).
