How to visualize different levels of connectors in a network

[maya]

Hi all, 

I'm currently looking for a way to visualize in a network the nodes connected to a node, as well as the nodes connected to those nodes (by double clicking for exemple). In other words, how could I visualise a person, his friends, and the friends of some of those friends on the same graph ? I'm using an ungrouped network, I tried using a hierarchical network, but I did not manage to affect colors depending on being in the first level variable or in the second. 

Could someone help me with that ? 

Thanks a lot in advance !

@FalkoSchulz and @Nascif_SAS's SASGF paper - From Traffic to Twitter - Exploring Networks in SAS Visual Analytics might provide you some ideas. http://support.sas.com/resources/papers/proceedings14/SAS045-2014.pdf

We also have a basic example of the expected data set structure in the user guide: https://support.sas.com/documentation/cdl/en/vaug/69957/HTML/default/viewer.htm#p06eosr7smtwskn1qphl... . The example uses a manager-employee relationship but is very similar to what you are trying to achieve. Make sure to include leaf-nodes at least once in the source column as per documentation - otherwise these aren't rendered due to missing node attributes.

Let us know how you go! Cheers, Falko
