I need to programmatically create Visio look-a-like diagrams as a drawing. Mostly we are going to create network layout diagrams similar to this one.

Is there a component that could speed-up the development or some technique we could use? Generally we could do this on our own via System.Drawing, but this might get tricky for more complex network diagrams as we would have to ensure there are no visual overlappings.
UPDATE: No Visio available. UPDATE 2: I would love if these could be eye candy
ConceptDraw has an eye candy graphics, awesome if you need it for presentations. There is a rapid draw technique for network templates and you can modify diagrams as you need.
Have you looked at the Visio API? It has a VBA feature. To recreate the Visio functionality using System.Drawing classes could get quite complex and need a herculean effort.
Graphviz may be of some use...
Have a look at this WPF Diagram Designer on CodeProject. It looks like it provides a lot of what you need, and WPF has unlimited potential for eye candy.
