title: D3.js Stacked Bar Chart adding percentage label on each bar
body: <p>I am trying to learn how to use D3.js and I am using this stacked bar code as a example: <a href="http://bl.ocks.org/mbostock/1134768" rel="nofollow">http://bl.ocks.org/mbostock/1134768</a>. I wanted to add a label on top of each bar that shows the percentage of wounds, other or disease. What code should I add to the original code from the example?</p>
  
  <p>Thanks</p>
