title: nvd3 chart showing grayscale
body: <p>I'm using nvd3 for the fist time and I'm having a tough time with the example found <a href="http://nvd3.org/examples/multiBarHorizontal.html" rel="nofollow">here</a>.</p>
  
  <p>My issue, is that none of the colors are actually showing.... instead I'm getting varying shades of gray (insert 50 shades of grey joke here). This is what I have in my <code>&lt;head&gt;</code> tag:</p>
  
  <pre><code>&lt;script src="d3.v3.min.js" charset="utf-8"&gt;&lt;/script&gt;
  
  &lt;script src="nv.d3.min.js" charset="utf-8"&gt;&lt;/script&gt;
  
  &lt;link rel="stylesheet" href="nv.d3.css"&gt;
  </code></pre>
  
  <p>My chart is just the standard horizontal bar chart with their data from the example linked above.... I'm not sure exactly what I'm doing wrong but if anyone has a suggestion let me know. </p>
  
  <p>Thanks as always.</p>
