[arangodb-google] How do I return a sub-graph in one query

[Allen Zhao]

Hi There,

Want to figure a way to query a sub graph. E.g. I want to query from a 
startVertex with depth 2 and list all nodes and edges in a sub-graph json.

I can use two queries to return nodes and edges and merge them into one. Is 
there a way to do that in one query?

{
  nodes: [
    {
      "_key": A,
      "x": 100,
      "y": 100
    },
    {
      "_key": B,
      "x": 200,
      "y": 200
    },
  ],
  edges: [
    {
      "_from": "A",
      "_to": "B"
    }
  ]
}
