            "data": [

                3,
                4,
                5
            ],
            "name": "China"
        }
    ],
    "legend": {

        "x": "center",
        "data": [

            "position": "bottom",
            "data": [
                "Nov",
                "Dec",
                "Jan",
                "Feb"
            ],
            "type": "category"
        }
    ],
    "yAxis": {}
}

代码在mac上也是一样可以运行的

使用chart.plot()可以调用浏览器来显示图表。
