javascript - D3.js JSON parse error -


while parsing inline json object d3.json(obj, function(error, root), working when i'm running locally, when run on tomcat server i'm getting xmlhttpparse error. searched on internet. answer found cors. there no clarity how achieve this. please me?

var obj = {  "name": "vis",  "children": [   {    "name": "votes",    "children": [     {"name": "200", "size": 200,"url":"1"},     {"name": "500", "size": 500,"url":"2"},     {"name": "300", "size": 300,"url":"3"},     {"name": "400", "size": 400,"url":"4"}    ]   },     {    "name": "reputation",     "children": [     {"name": "200", "size": 200},     {"name": "500", "size": 500},     {"name": "300", "size": 300},     {"name": "400", "size": 400}    ]   },   {    "name": "accepted answer",    "children": [         {      "name": "encoder",      "children": [       {"name": "accepted answer", "size": 500}      ]     }    ]   }  ] }; d3.json(obj, function(error, root) {     alert('error '+error);     alert('root: '+root);   if (error) return console.log(error); }

you misunderstanding d3.json used for. d3.json makes actual ajax request (hence why in documentation names chapter requests) literally trying fetch obj can't because doesn't need to. if want use d3.json, can move json object own file , reference doing d3.json(data.json, function(err, root)).

the result d3.json return literally object have declared. can assign variable name root.
