Here is the sample code representing pairplot: Pay attention to the usage of hue parameter which is passed categorical variable and used to map plot aspects to different colors. In other words, scatter plot matrix represents bi-variate or pairwise relationship between different combinations of variables while laying them in grid form. By default, the pairplot function creates a grid of Axes such that each numeric variable in data is shared in the y-axis across a single row and in the x-axis across a single column.
