title: Can I connect objects with javascript?
body: <p>I want to make an interface that looks like this</p>
  
  <p><img src="https://i.stack.imgur.com/lkwht.jpg" alt="enter image description here"></p>
  
  <p>So here is what the user can do </p>
  
  <p>1- Connect people to each other
  2- See some information about each person (the balloon)
  3- Move these objects around without them loosing their connections</p>
  
  <p>Then I want to save these connection information using ajax, so that I can see who is connected to who, I also need to redraw these diagrams next time the user sees the page.</p>
  
  <p>It seems like jsPlumb, paperjs, and raphael can all do this and a lot more, my question is which one is suitable for this need.</p>
