===============================================================
Plot PAGA-inferred trajectories (`scanpy.pl.paga/paga_compare`)
===============================================================

Depending on the selected options, it yields a plot of a graph representing
inferred trajectory, or a trajectory graph side-by-side with a scatter plot of
cells embedded to space of reduced dimensionality in png format.

It requires running PAGA, first.
