As it is not possible yet to transfer data from Neo4j to Gephi via .graphml- file without loss of information I tried to stream the data. Therefore the Graph Streaming Plugin for Gephi exists here.

Following the instructions and inserting Cypher-Code:

match path = (:p)-[:r]->(:m)
WITH path LIMIT 1000
with collect(path) as paths
call apoc.gephi.add(null,'workspace0', paths) yield nodes, relationships, time
return nodes, relationships, time

I receive: 

Can't read url http://localhost:8080/workspace0?operation=updateGraph as 
json: http://localhost:8080/workspace0?operation=updateGraph

What could be the problem?

Thank you in advance!

  • Did you try changing `workspace0` to `workspace1`? – Fabio Lamanna Aug 22 '17 at 14:45
  • @Fabio Lamanna, yes i did - same result – Grapheneer Aug 23 '17 at 08:24
  • Does the active Gephi window have workspace 0? – Yannis P. Aug 25 '17 at 12:59
  • @YannisP. How can I check that? It should be default.. – Grapheneer Sep 03 '17 at 10:50

    I made my research so in Gephi 0.9.1 the default workspace when you start the Gephi is workspace 1. So I would suggest to start Gephi, start the streaming server, uncheck SSL in the settings and in a new browser window, put in the the URL field: `http://localhost:8080/workspace1?operation=getGraph`. Provided that Gephi has loaded a graph, this request will return you a JSON with all graph info – Yannis P. Sep 03 '17 at 11:33

    This is what i get: Problem accessing /workspace1. Reason: Not Found – Grapheneer Sep 03 '17 at 11:35

    I was kind of having the same issue to begin with but then in the server settings I unchecked SSL and restarted Gephi and it worked for me at least – Yannis P. Sep 03 '17 at 11:57

For someone who has faced the similar issue, changing the language of Gephi (0.92) to English solved the problem.

  1. Turn off ssl in the Streaming Properties.
  2. Save
  3. Restart Gephi
  4. Load your file
  5. Start the streaming server

Go to

curl "http://localhost:8080/workspace1?operation=getGraph"

All @YannisP's work.., many thanks, I just tested it and put it in an answer (so people can find it more easily).
