Social network directed graph library for .NET

I am on a project where I have multiple users of a portal and they are connected to other users of the portal. Now we are asked to draw a “Social Network” relationship graph to see the relationships. The constraint is that this graph has to be seen in the web browser.

The graph has to be something like:

Is there any C# library or component to draw this type of graphs? We have already checked these:

• http://flare.prefuse.org/

• http://www.yworks.com/en/products_yfiles_practicalinfo_gallery.html

• .NET graph library around?

• http://quickgraph.codeplex.com/

• https://graphsharp.codeplex.com/

• http://sourceforge.net/projects/zedgraph/

But I want to check if you already used some other and your feedback.
