JavaScript Convert regular json to flare.json for d3.js?

I have come up with a series of regex transforms for this.

 #replace-this      #with-this

  ^\s*"             \{"name":"
  : \{\},           \},
  : \{\}            \}
  ": \{$            ","children":\[
  ^\s*\},           \]\},
  ^\s*\}            \]\}              


 #in that order

and just delete the first and last line (should be an extra { and ]} )

on applying these regex transforms,

this:

{
"a": {
"x": {
    "y": {
        "a": {}, 
        "z": {}, 
        "b": {}
    }
}, 
"c": {}, 
"b": {
    "c": {
        "d": {}
    }
}, 
"d": {} 
}

}

will become this:

{
"name": "a",
"children": [{
    "name": "x",
    "children": [{
        "name": "y",
        "children": [{
            "name": "a"
        },
        {
            "name": "z"
        },
        {
            "name": "b"
        }]
    }]
},
{
    "name": "c"
},
{
    "name": "b",
    "children": [{
        "name": "c",
        "children": [{
            "name": "d"
        }]
    }]
},
{
    "name": "d"
}]
}

which can then be used with some of the d3js examples.

Answer:1

You are going to have to write your own JSON or a function to dynamically change the JSON. Flare.json just follows a schema that adheres to Mike Bostock's d3 files.

I'll give you a hint. The schema that you wrote appears to be (in psuedocode)

array("name":"a", "children":array("name":"x","children":array(..... 

Basically, you need to create a multidimensional array in order to get the desired results. I don't know how you are getting your data, unfortunately, so I can't tell you much more. If using php use the json_encode method

echo json_encode($jsonArray)

or in javascript use json.stringify

var json = JSON.stringify($jsonArray)

in order to get the array to turn into json.
