title: Best solution to label nodes in SVG dynamic tree (using D3.js)
body: <p>I am trying to modify this D3.js example (<a href="https://gist.github.com/999346" rel="nofollow" title="Dynamic Node-Link Tree">Dynamic Node-Link Tree</a>) by adding a specific label (SVG text) to each node, but unsucessfully.</p>
  
  <p>If I understand correctly, after a brief look at SVG specs and D3 documentation, the best way would be to create SVG groups and move them around.</p>
  
  <p>Unfortunately, this is not working, as the transitions have no effect on the groups.
  Is there a simple(r) way I am not aware of?</p>
  
  <p>Many thanks.</p>
