如何使用外部json绘制Google组织结构图

Question

我有一个来自Google图表的带有父级子关系的json的组织结构图。我没有得到如何从下面的结构化json呈现组织结构图。如果有其他格式的json可以帮助我解决这个问题，或者像其他任何插件d3js，即使它很好。任何人都可以帮助我。这是下面的代码。

html

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<div id="chart_div"></div>

javascript

// Load the Visualization API and the piechart package.
google.charts.load('current', {'packages':['orgchart']});

// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var jsonData = $.ajax({
      url: "getjson.json",
      dataType: "json",
      async: false
      }).responseText;

  // Create our data table out of JSON data loaded from server.
  var data = new google.visualization.DataTable(jsonData);

  // Instantiate and draw our chart, passing in some options.
  var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));
  chart.draw(data, {width: 400, height: 240});
}
