关系图谱后端不给指向性字段使用children

这是后端给的json数据格式

echarts需要的数据格式

递归调用方法

const changeData = (data: any) => {

  
  let newData: any;
  if (Object.prototype.toString.call(data) === '[object Object]') {
    newData = [data]

  } else if (Object.prototype.toString.call(data) === '[object Array]') {
    newData = data
  }
  newData.forEach((item: any) => {
    chartsData.nodes.push({
      code: item.code,
      type: item.type,
      symbolSize: 100,
      name: item.name,
      itemStyle: {}
    })
    if (item.children.length > 0) {
      changeData(item.children)
    }

    if (item.children.length > 0) {
      item.children.forEach((value: any) => {
        chartsData.links.push({
          lineStyle: {},
