How to create graph projections from json file

Hello everyone!!

I'm looking for a way to resolve this problem. I need run graph algorithms on a graph that is in json format, like this (not the real, but similar):

{

   nodes: [

     {

       __id: "some_id",

       type: "NodeType",

      inE: ["node_id1", "node_id2", .....],

      outE: ["node_id100", "node_id200", .....]

     }, 

    .......

   ]  

}

The trouble is that I can't save this graph in Neo4j storage, is only for calculation. So my question, there is a way to create a Graph Projection from this json file??

You can try the graph construct method in the python client: https://neo4j.com/docs/graph-data-science/current/python-client/graph-object/#_constructing_a_graph

You'd need to map your json to the correct pandas dataframe formatting, but that will let you convert your json file directly into a graph projection.

Hello @eddylara0929 🙂

You should have a look at Virtual Graph from the APOC plugin.

Thanks I'll try it and comment later if result

@Cobra answer is valid for create graph, but i'm still facing issue of create a Graph Data Science graph projection for this virtual graph, as i need run GDS algorithms on this virtual graph

Can you share the JSON file and the query you used to create the virtual graph?

Thanks!!! This work!!!!
