netViz | Network Visualization Workshop | Data Visualization library

If have a simple example (for data see below) which I can visualize as follows:

[![network][1]][1]

My problem is, that I would like to use popups to display further information (which does not fit in the graph). The question is: How can I do this? I found many stuff but I was not able to make the example work, which might be caused, that I never programmed in Java. I should also say, that I don't need fancy/complicated 3D stuff. Just a popup would do the job!

Any help is highly appreciated!
