For work I made some (social) network diagrams in Excel, using a plugin called NodeXL. Unfortunately my workregulations don't allow the installation of such extensions.

I may however chose to use MS Visio 2007. Can anyone tell me if MS Visio 2007 is suitable for this purpose? Keep in mind i won't be able to use any extension for this program either!

The idea is that I only have to enter the vertices/nodes (list of names) and the edges (list of connections) and let the program weave this together into a network diagram. For instance I'll import a list of names such as "John" and "Sarah", and the connections "John-Sarah", and get a nice network with 2 nodes.

John - Sarah.

Obviously I'll have a lot more nodes, a lot more connections and will want to be able to filter/hide/import from Excel etc.

Looking forward to your answers!
