WebbWhen plotting multiple layers, use zorder to take control of the order of layers being plotted. The lower the zorder is, the lower the layer is on the map and vice versa. Without specified zorder, cities (Points) gets plotted below world (Polygons), following the default order based on geometry types. >>> WebbEach item in MultiPolygons represents one MultiPolygon and each MultiPolygon is comprised of n Polygons.
