-Why? Find communities, hubs, connections between (the X degrees of separation)
+Graph data can be very valuable for finding communities, hubs and connections between entities (the 6 degrees of separation). This is through the techniques of Social Network Analysis.

There are other graph databases worth considering like [OrientDB](http://www.orientdb.org/) or [Titan](http://thinkaurelius.github.com/titan/)
Major graph databases like these can be accessed using a common syntax called Gremlin or by writing a simple Java/Python/Ruby application. Queries can be tested in the built in data browser.

NetworkX is a social network analysis library for python. Many advanced analyses built in like finding communities within a graph. Also good for converting data into graphs.
