一起旋转一组 svg

Question

我有这个 fiddle : http://jsfiddle.net/kjow9nhv/2/

<div class='draw'>

<svg id='parent' width="100" height="100">
    <circle stroke-dasharray="7,7" cx="45" cy="45" r="45" stroke="gray" stroke-width="3" fill="white"/>
</svg>
<svg id='first' width="50" height="50">
 <circle stroke-dasharray="7,7" cx="25" cy="25" r="20" stroke="black" stroke-width="3" fill="red"/>
</svg>

<svg id='second' width="50" height="50">
    <circle stroke-dasharray="7,7" cx="25" cy="25" r="20" stroke="black" stroke-width="3" fill="red"/>
</svg>

<svg width="75" height="50">
 <rect width="40" stroke-linecap="round" height="5" x="25" y="43" style="fill:yellow;stroke-width:1;stroke:yellow;" />
</svg>

</div>

<div class='draw'>

  <svg id='parent' width="100" height="100">
    <circle stroke-dasharray="7,7" cx="45" cy="45" r="45" stroke="gray" stroke-width="3" fill="white" />

  </svg>
  <svg id='first' width="50" height="50">
    <circle stroke-dasharray="7,7" cx="25" cy="25" r="20" stroke="black" stroke-width="3" fill="red" />

  </svg>



  <svg id='second' width="50" height="50">
    <circle stroke-dasharray="7,7" cx="25" cy="25" r="20" stroke="black" stroke-width="3" fill="red" />

  </svg>


  <svg width="75" height="50">

    <rect width="40" stroke-linecap="round" height="5" x="25" y="43" style="fill:yellow;stroke-width:1;stroke:yellow;" />
  </svg>



</div>

如你所见，有两个圆（红色）和一个矩形（黄色），圆独立旋转，矩形连接两个圆的中心。

现在，我想做的是在外部（灰色）圆圈内将组（即两个圆圈和矩形）作为一个整体旋转。

这是我尝试过的方法：http://jsfiddle.net/kjow9nhv/3/..但不起作用。
