title: d3: Adding links to nodes in hierarchical edge bundling
body: <p>I'm a super beginner to d3/HTML/JS and I had a question about adding links to nodes in a graph. All of my code is based on: <a href="https://gist.github.com/mbostock/7607999" rel="nofollow noreferrer">https://gist.github.com/mbostock/7607999</a></p>

  <p>I'd like to add a link that leads to another html file for each node. Is that possible given how the code is structured?</p>
