To something like:
{"name": "Devices",
"children": [
{"name":"Udid", "size":"7f0dsda63274692ea4f0b66fec67a020158"},
{"name":"SerialNumber", "size":"P988KJSPQF938"},
{"name":"MacAddress", "size":"1HJUSUD031C4"},
{"name":"Imei", "size":""},
{"name":"EasId", "size":"ApKJSPQF193"},
{"name":"AssetNumber", "size":"7f0cda636b3305fea4f0b66fec9997267a020158"},
{"name":"DeviceFriendlyName", "size":"TMcKenz iPad iOS 7.1.4 F193 "},
{"name":"LocationGroupId",
"children": [
{"name":"Id","size":7488},
{"name":"Name","size":"MCM"}
]
},
{"name":"UserId",
"children": [
{"name":"Id","size":6418},
{"name":"Name","size":"Tom McKenz"}
]
},
{"name":"UserName", "size":"TMcKenz"},
{"name":"UserEmailAddress", "size":"TMcKenz#awaw.com"}
]
}
Not sure what is the best practice here: is it possible to use D3.nest or do you need to iterate through all the nodes and change to 'name' and 'children' accordingly.
