=================
Zoom region inset
=================

This example shows how to add a region in the stereographic projection as a zoomed
inset inside another stereographic projection, following the procedure in `this
Matplotlib example
<https://matplotlib.org/stable/gallery/subplots_axes_and_figures/zoom_inset_axes.html>`__.
