这里写图片描述

二、数据结构
data.json:
{
“name”:”中国”,
“number”:”2000”,
“children”:
[
{
“name”:”浙江” ,
“number”:”100”,
“children”:
[
{
“name”:”杭州” ,
“number”:”100”
},
{
“name”:”宁波” ,
“number”:”200”
},
{
“name”:”温州” ,
“number”:”300”
},
{
“name”:”绍兴”,
“number”:”400”
}
]
},
{
“name”:”广西” ,
“number”:”500”,
“children”:
[
{
“name”:”桂林”,
“number”:”100”
},
{
“name”:”南宁”,
“number”:”200”
},
{
“name”:”柳州”,
“number”:”300”
},
{
“name”:”防城港”,
“number”:”400”
}
]
},
{
“name”:”黑龙江”,
“number”:”500”,
“children”:

“name”:”大庆”,
“number”:”400”
}
]
},
{
“name”:”新疆” ,
“number”:”500”,
“children”:
[
{
“name”:”乌鲁木齐”,
“number”:”100”
},
{
“name”:”克拉玛依”,
