How to use Seaborn's relational plot function to create visualizations in Python?

This query is related to a recent query I posted which was regarding Categorical plots in Seaborn and in this query, I wanted to learn about relational plots and the function available to create such plots using Seaborn library. I know there is a function for this but I am unaware of its name, the parameters of this function, and how I can use it to create plots like scatter plots and line plots. I would appreciate if anyone can help me with this using some example codes.
