我在a.json文件中，进行如下定义：
[
{"name": "普洱市", "dept":"内科", "diagnosis":"胃癌", "value":1},
{"name": "红河哈尼族彝族自治州", "dept":"妇产科", "diagnosis":"肝癌", "value":2},
{"name": "文山壮族苗族自治州", "dept":"外科", "diagnosis":"肺癌", "value":3},
{"name": "曲靖市", "dept":"内科", "diagnosis":"胃癌", "value":4},
{"name": "楚雄彝族自治州", "dept":"妇产科", "diagnosis":"肝癌", "value":5},
{"name": "大理白族自治州", "dept":"外科", "diagnosis":"肺癌", "value":6},
{"name": "临沧市", "dept":"内科", "diagnosis":"胃癌", "value":7},
{"name": "迪庆藏族自治州", "dept":"妇产科", "diagnosis":"肝癌", "value":8},
{"name": "昭通市", "dept":"外科", "diagnosis":"肺癌", "value":9},
{"name": "昆明市", "dept":"内科", "diagnosis":"胃癌", "value":10},
{"name": "丽江市", "dept":"妇产科", "diagnosis":"肝癌", "value":11},
{"name": "西双版纳傣族自治州", "dept":"外科", "diagnosis":"肺癌", "value":12},
{"name": "保山市", "dept":"内科", "diagnosis":"胃癌", "value":13},
{"name": "怒江傈僳族自治州", "dept":"妇产科", "diagnosis":"肝癌", "value":14},
{"name": "玉溪市", "dept":"外科", "diagnosis":"肺癌", "value":15},
{"name": "德宏傣族景颇族自治州", "dept":"内科","diagnosis":"胃癌", "value":15}
]
但是浏览器报这个json文件有语法错误，请问我应该怎么修改？
