Currently the only way to do this is to rebuild the graph in each iteration by adding more vertices and edges to the source RDDs, then calling the graph constructor. I'm working on a way to support this more efficiently (SPARK-2365 <https://issues.apache.org/jira/browse/SPARK-2365>), but GraphX doesn't take advantage of this yet.
