title: Is it possible to rotate a group after we drag drop the certain object onto them in konvajs?
body: <p>I'm trying to animate the weighing machine i.e. if the user drag and drops the balls on the weights of the machine, the machine should move according to the weights of the balls afterward.</p>
  <p>The weighing machine would not be animated from the start but will move when the user puts some balls on either side of the machine.</p>
  <p>I'm using konvajs, how can I make this possible?</p>
