title: Stop Force Layout on d3js and start free dragging nodes
body: <p>I'm using the force layout to represent a directed unweighted network. My inspiration comes from the following example: <a href="http://bl.ocks.org/mbostock/1153292" rel="noreferrer">http://bl.ocks.org/mbostock/1153292</a></p>
  
  <p><img src="https://i.stack.imgur.com/vltVP.jpg" alt="enter image description here"></p>
  
  <p>Since my own data are really a mess, I'd like to stop the layout and move nodes by dragging them manually. I'd also like that the movement of a node doesn't change the position of others. And it's necessary that links become longer, to reach the node which has been moved.</p>
  
  <p>Is there a simple way to do this?</p>
