如何在d3js中垂直树

我目前正在研究由d3.js创建的树，我发现了一个非常有用的示例，但是我想出了一种使树垂直的方法，这是我的代码。

<div class="dashboard-block-content" >
    <style>

    .node circle {
      fill: #fff;
      stroke: steelblue;
      stroke-width: 1.5px;
    }

    .node {
      font: 10px sans-serif;
    }

    .link {
      fill: none;
      stroke: #ccc;
      stroke-width: 1.5px;
    }

    </style>
    <script src="//d3js.org/d3.v3.min.js"></script>
    <script>
