echart 徑向關係網圖 多重關係圖
一、需求，實現 網頁連接分享 閱讀瀏覽量關係圖，不一樣分支不一樣顏色，同個分流同一個顏色。
二、使用echart進行數據渲染，對option配置動態渲染。

須要data數據格式：web
{
"data": {
"id": null,
"passportId": null,
"clientType": null,
"houseVideoId": null,
"status": null,
"forwarderAccountId": null,
"browserAccountId": null,
"firstForwardId": null,
"createTime": null,
"updateTime": null,
"createUserId": null,
"updateUserId": null,
"browserIcon": null,
"browserName": null,
"num": null,
"children": [
{
"id": null,
"passportId": null,
"clientType": null,
"houseVideoId": null,
"status": null,
"forwarderAccountId": null,
"browserAccountId": "AA",
"firstForwardId": null,
"createTime": null,
"updateTime": null,
"createUserId": null,
"updateUserId": null,
"browserIcon": "AA_icon",
"browserName": "AA_name",
"num": 48,
"children": [
{

"houseVideoId": null,

"browserIcon": "AAA_icon",
"browserName": "AAA_name",
"num": 32,
"children": null,
"itemStyle": "#46bfd1",
"lineStyle": "#46bfd1"
},
{
"id": null,
"passportId": null,
"clientType": null,
"houseVideoId": null,
"status": null,
"forwarderAccountId": "AA",
"browserAccountId": "AAB",
"firstForwardId": null,
"createTime": null,

"browserIcon": "AAB_icon",
"browserName": "AAB_name",

"children": null,
"itemStyle": "#46bfd1",
"lineStyle": "#46bfd1"
}
],
"itemStyle": "#46bfd1",
"lineStyle": "#46bfd1"
},
{
"id": null,
"passportId": null,
"clientType": null,
"houseVideoId": null,
"status": null,
"forwarderAccountId": null,
"browserAccountId": "AE",
"firstForwardId": null,

"lineStyle": "#46bfd1"
}
],
"itemStyle": null,
"lineStyle": null
},
"code": 200,
"message": "success"
}
本例子後臺提供數據格式：canvas
{
"data":
{

"passportId": null,
"clientType": null,
"houseVideoId":null,

"createTime": null,
"updateTime": null,
"createUserId": null,
"updateUserId": null,
"browserIcon": null,
"browserName": null,
"num": null,
"children":[{
"id": null,
"passportId": null,
"clientType": null,
"houseVideoId": null,
"status": null,
"forwarderAccountId": null,
"browserAccountId": "ozkr5v_vVBvwDtzUEg0zi7itZHPc",
"firstForwardId": null,

"createUserId": null,
"updateUserId": null,
"browserIcon": "http://thirdwx.qlogo.cn/mmopen/vi_32/DYAIOgq83erFBhKwBzHYyN6PwKb71GuGD9z6r3hVAxnD2nZ66zUS2vghR8cbxIldL42610kB7gEGC1eEhQdCsw/132",
"browserName": "DerMing_You",
"num": 4,

"itemStyle": "#46bfd1",
"lineStyle": "#46bfd1"
}, {

"houseVideoId": null,
"status": null,
"forwarderAccountId": null,
"browserAccountId": "ozkr5vzzFtimKuCZA0Igwn18Wgek",
"firstForwardId": null,
"createTime": null,
"updateTime": null,
"createUserId": null,
"updateUserId": null,
"browserIcon": "",
"browserName": "Cubi燁",
"num": 2,
"children": null,
"itemStyle": "#7a84f5",
"lineStyle": "#7a84f5"
}],
"itemStyle":null,
"lineStyle":null
},
"code": 200,
"message": "success"
}

主要要點在於將後臺給的數據 從新組合爲所須要的data數據格式。
本案例後臺給到數據返回的dataStr.children數據格式爲：
