To connect the graph visualization capabilities of Gephi with Spark GraphX graphs, we need to address a way to communicate between the two. The canonical candidate for doing so is Gephi's Graph Exchange XML Format (GEXF), a description of which can be found at https://gephi.org/gexf/format/. A very simple example of how graphs are described in this format is displayed in the following code listing:
<?xml version="1.0" encoding="UTF-8"?><gexf xmlns="http://www.gexf.net/1.2draft" version="1.2"> <meta lastmodifieddate="2009-03-20"> <creator>Gexf.net</creator> <description>A hello world! file</description> </meta> <graph mode="static" defaultedgetype="directed"> <nodes> <node id="0" label="Hello" /> <node ...
