Development and implementation of the problem of social relations

Question

I am using C # + VSTS 2010 + .NET 4.0 + ASP.NET + IIS 7 on Windows 7.

I currently have some relationships of people stored in a database. I am wondering how to realize the same visual effect that is shown in the demo below?

Are there any C # libraries ready to use? Better if open source and free. :-)
