title: Same d3.js Is throwing Invalid Charecter Error
body: <p>js I just downloaded d3.js and included in cubism example It worked and the same d3.js is giving invalid charecter error when I tried to load reel example through IIS.</p>
  
  <p>Below is the error at which it is throwing error.
  I agree there are some special charecters in this line but it is handeled in <a href="http://square.github.com/cubism/" rel="nofollow">cubism exaple</a> but why not in <a href="http://bl.ocks.org/1256572" rel="nofollow">showreel</a> ?</p>
  
  <pre><code>var sinφ0 = Math.sin(φ0), n = (sinφ0 + Math.sin(φ1)) / 2, C = 1 + sinφ0 * (2 * n - sinφ0), ρ0 = Math.sqrt(C) / n;
  </code></pre>
  
  <p>I am trying to laod through IIS. Any working code for this showreel example ?</p>
  
  <p>And is there any way to make these graphs vertical Instead of horizontal?</p>
  
  <p>And Instead of loading local files If I load directly from given url's</p>
  
  <p>then these 3 below URLs are returning 404 error, any code for these 3 files ?</p>
