Seaborn

Seaborn (https://seaborn.pydata.org/) is part of the PyData family of tools and is a visualization library based on Matplotlib with the goal of creating statistical graphs more easily. It can operate directly on DataFrames and series, doing aggregations and mapping internally. Seaborn uses color palettes and styles to make visualizations consistent and more informative. It also has functions that can calculate some statistics, such as regression, estimation, and errors. Some specialized plots, such as violin plots and multi-facet plots, are also easy to create with Seaborn.
