A box plot (or box-and-whisker plot) is a graphical representation of data that shows the distribution through their quartiles. It highlights the median, the first quartile (Q1), the third quartile (Q3), and potential outliers. Box plots are useful for comparing distributions between different datasets.

Using Matplotlib

The matplotlib.pyplot module provides a boxplot() function to create box plots. Here's a basic example:

This code generates a simple box plot for a dataset created using numpy.random.normal().

Customizing Box Plots

Matplotlib allows extensive customization of box plots. For example, you can create notched box plots, change the orientation, and customize colors and styles:
