title: SVG disappears in firefox on transform
body: <p>In Safari all is well, in Firefox, the svg is not the correct size and when I transform it, it disappears.  I'm running Safari Mac 5.1.7 and Firefox Mac 15.0.</p>
  
  <p>The code was created with d3 but I've just supplied the html.</p>
  
  <p>Now you see it:  <a href="http://bl.ocks.org/3531350" rel="nofollow">http://bl.ocks.org/3531350</a></p>
  
  <p>Now you don't:  <a href="http://bl.ocks.org/3531267" rel="nofollow">http://bl.ocks.org/3531267</a> (edited so it works now)</p>
  
  <p>I imagine I have made a foolish mistake somewhere but I just can't see it!</p>
