Overview
matplotlib is the most popular Python library for producing plots and other two-dimensional data visualizations.

Difference between Plot and Scatter
A "plot" expects two X and Y vectors as argument, which are expected to have the same length, and it creates a 2D line that includes the (X,Y) points. The points are connected by line segments.
Visualization Style
The visualization style can be set globally with:
import matplotlib.pyplot as plt
plt.style.use(<style-name>)
where available style names can be obtained with:
import matplotlib.pyplot as plt
print(plt.style.available)

_mpl-gallery
_mpl-gallery-nogrid

Interesting styles:
- seaborn-v0_8-whitegrid
Otherwise, style elements like axes, gridlines, line color and width can be set up individually.
Color Palette
A list of colors that can be used to change the colors in plots, so they don't look the same. This line pulls the default colors from the style.
