Basemap and chrome

A minimal map: European countries as background, France lifted by a drop shadow, department boundaries on top, plus the chrome (title, scale bar, source). Mainland France is framed in Lambert-93 and the overseas departments are drawn as cartouches.

A map is built by adding layers and elements to a Map with +. The order of the elements does not matter: the map is drawn when it is rendered.
