Visualization of JanusGraph with Gephi plugin

[haifa.a...@gmail.com]

Hello all,

I begin in JanusGraph and Gephi, I follow the instructions of the chapter 3 of JanusGraph to use the Graph of the gods, everything works well. Now I will visualize my graph on Gephi, so I follow the instructions on Tinkerpop.apche using Gephi plugin. The test is ok if I create the graph on gremlin console, but I can’t visualize the graph of the Gods when I tried to submit it to Gephi.

The code I used to load graph

gremlin> graph = JanusGraphFactory.open('conf/janusgraph-berkeleyje-es.properties')

==>standardjanusgraph[berkeleyje:../db/berkeley]

gremlin> GraphOfTheGodsFactory.load(graph)

==>null

gremlin> g = graph.traversal()

==>graphtraversalsource[standardjanusgraph[berkeleyje:../db/berkeley], standard]

 

The code I tried to use to submit the graph to Gephi

gremlin> :plugin use tinkerpop.gephi

==>tinkerpop.gephi activated

gremlin> graph = TinkerFactory.createModern()

==>tinkergraph[vertices:6 edges:6]

gremlin> :remote connect tinkerpop.gephi

==>Connection to Gephi - http://localhost:8080/workspace1 with stepDelay:1000, startRGBColor:[0.0, 1.0, 0.5], colorToFade:g, colorFadeRate:0.7, startSize:10.0,sizeDecrementRate:0.33

gremlin> :> graph

==>tinkergraph[vertices:6 edges:6]

==>false

Hi Haifa,

Try this.

gremlin> :plugin use tinkerpop.gephi

==>tinkerpop.gephi activated

gremlin> :remote connect tinkerpop.gephi

==>Connection to Gephi - http://localhost:8080/workspace1 with stepDelay:1000, startRGBColor:[0.0, 1.0, 0.5], colorToFade:g, colorFadeRate:0.7, startSize:10.0,sizeDecrementRate:0.33

gremlin> :> graph = JanusGraphFactory.open('conf/janusgraph-cql-es.properties');   //here you can load the config file you are using

==>standardjanusgraph[cassandrathrift:[127.0.0.1]]

gremlin> :> GraphOfTheGodsFactory.load(graph);

This worked for me.
Hope it will work for you as well.

Thanks,
Abhay

Hi, 

Thank you a lot. 

Now I visualize the graph of gods on Gephi but not all the nodes (not all edges) I have this warning "Adding thi property for key [~T$ShemaName] and value [rt name] violates a uniqueness constraint [SystemIndex #~T$SchemaNam].

Thanks,

Haïfa

Hi Haifa,

As Name property key is already present so its not possible to add same property key twice.
you can just try to add value.
Eg.
g.addV("LabelName").property("name","Haifa");
g.tx().commit();

Thanks,
Abhay
