stuff isn't escaped right

If you use this json file:

var kTree = {
  "data": {
    "$area": 89118673, 
    "$dominant_symbol": ""
  }, 
  "name": "[everything] 89.1m", 
  "children": [
    {
      "data": {
        "$area": 19992565, 
        "$dominant_symbol": "code"
      }, 
      "name": "[path] 20.0m", 
      "children": [
        {
          "data": {
            "$area": 43, 
            "$symbol": "code"
          }, 
          "name": "\" <meta http-equiv='refresh' content='0;%s'>\" 43"
        }, 
      ]
    }
  ]
}

then the treemap will be replaced with a useless page ("%s") once it's done loading. (Happens when using it with chromium.)
