Get data from NEO4j

[Andreas Dernbauer]

Hi 

I am new to d3.js, hopefully someone can help me.

I tried since days to get data from NEO4J within the d3.js.

As far as I have learned it must be something with d3.xhr but it doesn't work

I tried the following:

var sql ='{"statements":[{"statement":"MATCH (a)-[:`srcChildOf`]->(b) RETURN a,b",   "resultDataContents":["graph"]}]}';
d3.xhr('http://localhost:7474/db/data/transaction/commit',sql,function(error,data){})

can someone help me.

Thank you regards from Vienna.

Not sure if you found this:
http://neo4j.com/developer/guide-data-visualization/

Looks like neo4j is expecting a POST even for a query.

To do that in d3, you'd use d3.json.post
https://github.com/mbostock/d3/wiki/Requests#post

So maybe something like this:

d3.json('http://localhost:7474/db/data/transaction/commit')
  .post(
      JSON.stringify({

      statements: [{
          statement: "MATCH (a)-[:`srcChildOf`]->(b) RETURN a,b",      
          resultDataContents: ["graph"]
        }]

    }),
  function(error, data){
    // do the thing
  }
))

thank you for you help but I receive error 415 

Failed to load resource: the server responded with a status of 415 (Unsupported Media Type)

That is a bit cryptic! Looks like this is not unheard-of:

Check the full body of the response and the request in your F12 browser console, and you might find something. If nothing useful comes of that, pot it here.
