========================================
GridSpec with variable sizes and spacing
========================================
This example demonstrates the use of `.GridSpec` to generate subplots,
the control of the relative sizes of subplots with *width_ratios* and
*height_ratios*, and the control of the spacing around and between subplots
using subplot params (*left*, *right*, *bottom*, *top*, *wspace*, and
*hspace*).
