Idea to switch the order of matplitlib/seaborn: - We first see seaborn as the high-level plotting library, and only afterwards learn about matploltib being the underlying library for both pandas plot and seaborn - Matplotlib is then the library with which you can further tweak the resulting plot from pandas/seaborn, or set up custom subplots if needed - We would then need to remove all direct matplotlib interaction from the early pandas notebooks and first case study? (e.g. `fix, ax = plt.subplots() ...` where this is not strictly needed)
