title: Walkthrough of constituent parts of D3 Hierarchical Edge Bundling example
body: <p>I would love to understand and recreate a similar version of this object:</p>
  
  <p><a href="http://mbostock.github.io/d3/talk/20111116/bundle.html" rel="nofollow">http://mbostock.github.io/d3/talk/20111116/bundle.html</a></p>
  
  <p>This is an example - but I cannot workout how it works or where the code for it lies?</p>
  
  <p>Can somebody either break the sample apart for me into its constituent parts (js, html, css) which would allow me to navigate and reverse engineer how it works, or point me at an appropriate tutorial explaining that sample?</p>
  
  <p>Cheers</p>
