They are based on the concept of a minimum bounding rectangle - the smallest rectangle that contains an entire geometri...
To create a line plot in Seaborn, we can use one of the two functions: lineplot() or relplot(). Overall, they have a lot of functionality in common, together with identical parameter names. The main difference is that relplot() allows us to create line plots with multiple lines on diffe...
