Seaborn is a graphic library built on top of Matplotlib. It allows to make your charts prettier, and facilitates some of the common data visualisation needs (like mapping a color to a variable or using faceting). This page gives
general tips concerning this awesome library. Visit individual chart sections if you need a specific type of plot. The Seaborn documentation is also very well done and help going further. Most of the customisations that work
for Matplotlib work for Seaborn, so do not hesitate to visit the Matplotlib page of the gallery. Last but not least, note that loading seaborn before a matplotlib plot allows you to benefit from its well looking style!
If you are a newbie in dataviz and seaborn, I suggest to follow this datacamp online course. The third part is dedicated to seaborn.
