将一组svgs一起旋转

Question

我有这个小提琴：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>

如您所见，有两个圆圈（红色）和一个矩形（黄色），圆圈独立旋转，矩形连接两个圆圈的中心。

现在，我想要做的是将组（即两个圆圈和矩形）作为一个单元旋转在外（灰色）圆圈内。

这就是我尝试过的：http://jsfiddle.net/kjow9nhv/3/ ..但不起作用。
