title: Best javascript library to create and interactive flow chart
body: <p>I would like to create an interactive 'problem solving' type flow chart that is made up out div elements.</p>
  <p>I would like to do something very similar to what the new york times have done in this example...</p>

  <p>Someone suggested Raphael so I've been learning a bit of that and it's awesome.</p>
  <p>Is there any other library worth considering?</p>
  <p>Also if Raphael is suitable for this task, is it a widely used library? If I am going to learn new skills It's in my best interest to learn popular code so I can re apply it with different jobs I get, not some exotic thing that Ill never use or no one will ever want me to use again.</p>
