What is a pairs plot (or scatter plot matrix), and which seaborn function can create it?
Explanation
A pairs plot, created with `seaborn.pairplot`, is an excellent tool for initial data exploration. It creates a matrix of axes, showing scatter plots for each pair of variables in the off-diagonal axes and a univariate distribution (like a histogram or density plot) for each variable on the diagonal axes.
