This example shows how to import a JSON file exported by Gephi. The two
  options available for the import are
  available through the checkboxes. You can download the Gephi JSON exporter
  here:
  
https://marketplace.gephi.org/plugin/json-exporter/.
  All of Gephi's attributes are also contained within the node elements. This
  means you can access all of this data through the DataSet.
