title: Draw a line between two draggable elements
body: <p>I have a series of divs that are draggable upon clicking them. When you release the mouse, the div will animate back into its original position. </p>
  
  <p>I want to be able to draw a straight line between any two of these draggable divs. The line should start at the center of one div and end at the center of the second div. When I click and drag one of the divs, the line should remain connected to both divs, stretching/shrinking as needed dependent upon the amount of space between the two divs. When the mouse is released, the line should still remain connected to the divs. </p>
  
  <p>I have the draggable divs working correctly. I'm just really not sure at all on how to solve for the line drawing portion. Any guidance would be very much appreciated. </p>
