Exercise 1: Insert a legend object
Lesson 7: Create a Legend
Create a legend that lists the layers in your map, using a color key that identifies each one. The legend is an object that you drop into place on your map.
Fine-tune the legend to show only the layers you want, in the order in which you want them (even if this order is different from your draw order).
