Question

我想在D3树形图的每个节点中添加圆环图（用圆环图替换树中的圆形节点）

以下是我的代码。我想用每个节点中的圆环图替换圆形节点，并使用从样本json中读取的不同数据。

＆＃13;

// Sample JSON Data 
var jsondata = {
  "name": "CERT",
  "children": [{
    "name": ""
  }, {
    "name": ""
  }, {
    "name": "DNS",
    "children": [{
      "name": "FW",
      "children": [{
        "name": ""
      }, {
        "name": ""
      }, {
        "name": "ADC",
        "children": [{
          "name": ""
        }, {
          "name": ""
        }, {
          "name": "SERVERS",
          "children": [{
            "name": ""
          }, {
            "name": ""
          }]
        }]
      }]
    }]
  }, {
    "name": "FW",
    "children": [{
      "name": ""
    }, {
      "name": ""
    }, {
      "name": "DNS",
