{
  "title": "My Report",
  "datasets": [
    {
      "type" : "lineChart",
      "description" : "My first chart",
      "xaxis" : "Year"
      "yaxis" : "Total sales"
      "data" :
      {
        "2010" : 50,
        "2011" : 33,
        "2012" : 17,
        "2013" : 87,
      }
    }
  ]
}

json数据会在Explorer中获取,并用来生成图表或列表
