Gephi plugin and AWS Neptune

[charles...@trustscience.com]

I'm playing around with interactive graph visualization tools and I'm currently attempting to use the Gephi plugin.  I've worked through the tutorial and except for a few caveats that I've mostly worked out I have a question that doesn't seem to be addressed by that plugin.

Namely, how do I visualize a graph in AWS Neptune using the gephi plugin?  I feel like this should be possible.

I can execute gremlin traversals from a console on the host where I run gephi.  I can great graphs in Gephi using the TinkerFactory graph.  Now how do I link them together?

Thanks for your help in advance.

I don't think you can do that directly. The Gephi plugin relies on having a local graph instance and Neptune doesn't allow for that. One thing you can try though is to subgraph() the portion of your Neptune graph that you want to analyze in Gephi and get that as a TinkerGraph locally, then you can work with that local subgraph as the TinkerPop instructions explain.

Ahh thanks.  I'll try that.

Were you able to make Gephi work with a subgraph exported from AWS Neptune ?

I have a graph exported but no nodes or edges show up in Gephi workspace

gremlin> :> graph
==>tinkergraph[vertices:2 edges:2]
==>false

No errors are reported in the console.

I have Gephi 0.9.2 plugin

If you have a TinkerGraph I would expect things to work, however I noticed that according to our reference documentation we've only tested these changes on Gephi 0.9.1 and the 1.0.3 version of the streaming plugin. I've known patch releases of the streaming plugin to break our integration so if you have a newer version then it could be a problem I'm pretty sure that I've also known patch releases of gephi to break the streaming plugin. Luckily they don't update terribly often but that integration has always been troublesome. I've often wanted to deprecate it given the other visualization options that now exist on the TP3. Perhaps you should try to use those specific versions of the Gephi and the plugin to see if it works and if they don't then we'll need a JIRA ticket created at which point a patch would be welcome (or if there is no movement on that I might suggest deprecation somewhere down the line).

Thanks for getting back to me.

I found the issue was in my yaml as I was not using the correct serializer.

I was able to display my graph in Gephi
