The pairplot function creates a grid of Axes such that each variable in data will by shared in the y-axis across a single row and in the x-axis across a single column. That creates plots as shown below.

The pairplot plot is shwon below. Its using the iris flower data set. The data set has 4 measurements: sepal width, sepal length, petal_length and petal_width. The data is mapped in the grid below. Because there are 4 measurements, it creates a 4x4 plot.
If you prefer a smaller plot, use less variables. For instance, if you only want sepal_width and sepal_length, tha would create a 2x2 plot.
g = sns.pairplot(iris, vars=["sepal_width", "sepal_length"])
You can change the shape of the distribution.
g = sns.pairplot(iris, diag_kind="kde")
