In this example, you can see how to render a legend in the maps. A legend item denotes the value of a shape. Any number of legend items can be added to the legend. You can bind the desired colors to the shapes, if its values are within the specified range using the
ColorMapping property. You can also show or hide color mapping related to population density when toggling the legend item.
