Getting Data from NEO4J and now ?

[Andreas Dernbauer]

Hi hopefully someone can help,

I connect to NEO4J via REST API and got some data back.

d3.json(neo4JEndPointURL)

        .header("Content-Type", "application/json")

        .post(

        JSON.stringify({

            statements: [{

                statement: "MATCH (a)-[:`srcChildOf`]->(b) RETURN a,b",

                resultDataContents: ["graph"]

            }]

The result looks like:

Under the object.graph there are a nodes array with two elements 

The NEO4J guid says: 

Converting Neo4j Query Results to D3 JSON

function idIndex(a,id) {
for (var i=0;i<a.length;i++) {
if (a[i].id == id) return i;}
return null;
}
var nodes=[], links=[];
res.results[0].data.forEach(function (row) {
row.graph.nodes.forEach(function (n) {
if (idIndex(nodes,n.id) == null)
nodes.push({id:n.id,label:n.labels[0],title:n.properties.name});
   });
links = links.concat( row.graph.relationships.map(function(r) {
return {start:idIndex(nodes,r.startNode),end:idIndex(nodes,r.endNode),type:r.type};
   }));

});

viz = {nodes:nodes, links:links};

But what is a and id which parameter should I overhanded to that function ? 

 

Thank You !
