Javascript 如何将url中的json值应用于双层分区D3布局

Javascript 如何将url中的json值应用于双层分区D3布局,javascript,json,d3.js,Javascript,Json,D3.js,第三天过去了,我无法更改双层分区(或Sunburst)d3的代码来显示我的数据。 我使用以下json代码实现了此布局: { "children": [ { "name": "المصاريف", "children": [ { "name": "Expense_1", "colour": "rgba(255, 148, 42)", "children": [ {

第三天过去了,我无法更改双层分区(或Sunburst)d3的代码来显示我的数据。 我使用以下json代码实现了此布局:

{
  "children": [
    {
      "name": "المصاريف",
      "children": [
        {
          "name": "Expense_1",
          "colour": "rgba(255, 148, 42)",
          "children": [
            {
              "name": "ExpSubCat1_1",
              "size": 8,
              "colour": "rgba(255, 148, 42,0.95)"
            },
            {
              "name": "ExpSubCat1_6",
              "size": 15,
              "colour": "rgba(255, 148, 42,0.45)"
            },
          ]
        },
        {
          "name": "Expense_2",
          "colour": "rgb(255, 148, 42)",
          "children": [
            {
              "name": "ExpSubCat2_1",
              "size": 10,
              "colour": "rgba(255, 148, 42,0.75)"
            },
            {
              "name": "ExpSubCat2_2",
              "size": 5,
              "colour": "rgba(255, 148, 42,0.65)"
            }
          ]
        }
      ]
    },
  ]
}
这是我的json数据,来自url:

因此,我需要更改布局以接受我的json数据并将节点添加到圆中,但以下是我所做的,没有结果…:

$.ajax({
    type: "GET",
    contentType: "application/json; charset=utf-8",
    url: '{{ url_for("diffs.api_domains", file_id=file.id) }}',
    dataType: 'json'
}).done(function(result, error) {

  partition
      .value(function(d) { return d.size; })
      .nodes(error)
      .forEach(function(d) {
        d.sum = d.value;
      });

      .value(function(d) { return d.sum; });

  var g = svg.selectAll("g")
      .data(partition.nodes(result))
      .enter().append("g");

  var path = g.append("path")
    .attr("d", arc)
    .style("fill", function(d) { return color(d.name); })
    .on("click", click)
    .each(stash);
});
我的数据被添加到
result
参数中,我认为
d.name
d.size
d.value
必须替换为我的json中的数据参数,但我不知道需要做什么更改

如果你知道如何解决这个问题,任何提示或解决方案都会对我有很大帮助。如果我的解释不清楚或者有什么不合理的地方,请告诉我
