"""
================
Nested Gridspecs
================
GridSpecs can be nested, so that a subplot from a parent GridSpec can
set the position for a nested grid of subplots.
Note that the same functionality can be achieved more directly with
`~.Figure.subfigures`; see
:doc:`/gallery/subplots_axes_and_figures/subfigures`.
