def basemap(self, **kwargs):
r"""
Plot base maps and frames for the figure.
Creates a basic or fancy basemap with axes, fill, and titles. Several
map projections are available, and the user may specify separate
tick-mark intervals for boundary annotation, ticking, and [optionally]
gridlines. A simple map scale or directional rose may also be plotted.
At least one of the parameters ``frame``, ``map_scale``, ``rose`` or
``compass`` must be specified.
