In this tutorial, we use the Arrowhead iExpression to attach an arrowhead to a path. If you change the path, the arrowhead updates
automatically and its appearance can be changed easily.
Creates an arrow head that can be attached to any shape. The arrow head is a separate path such that it can be styles independently of the shape it is attached to.
The appearance of the arrowhead can be controlled in full detail using the iExpressions parameters.
