Remarks

To configure a VectorMap legend collection, use a multiline lambda expression. In this case, a lambda parameter performs the role of a collection factory, and its Add() method adds a new item to the collection. The Add() method returns VectorMapLegendBuilder whose methods you can use to configure an item.
