title: Freezing force directed network graph and make draggable in D3
body: <p>I am trying to freeze a force directed network in d3 completely! I have tried setting the friction value to 0, but the network becomes more condensed and the nodes still hover slightly. </p>
  
  <pre><code>var force = d3.layout.force()
  .charge(-220)
  .linkDistance(70)
  .friction(0);
  </code></pre>
  
  <p>I also want my nodes to be draggable i.e. move position when they are dragged. </p>
  
  <p>Ultimately, I'm trying to get something similar to Cytoscape js which looks like <a href="http://cytoscape.github.com/cytoscape.js/" rel="nofollow">this</a>. </p>
  
  <p>Thanks!</p>
