Keyword arguments
-----------------
fontsize : int
Font size to use for the plot titles, and axes ticks and labels.

tight_layout_rect : Sequence[float]
A rectangle (left, bottom, right, top) in the normalized figure
coordinate that the whole subplots area (including labels) will
fit into. Defaults to (0, 0, 1, 1).
suptitle : str
The figure title. Defaults to an empty string.
