title: How to create a "Pick Whip" (Adobe After Effects) in Swing
body: <p>In Adobe After Effects there is something called a "pick whip". It allows you to click on a dot on one object and drag a line from that dot to another element, making a connection between the two. I would like to duplicate this feature in my Java program using swing. I honestly have no idea where to start.</p>
  
  <p>If I've done a bad job explaining what I mean, please comment so I can improve it. If there is some way outside of Swing to do this, I'm willing to try it.</p>
  
  <p>Here are some examples of what I am trying to achieve:
