Seaborn

Seaborn is a Python visualization library for statistical plotting. It comes equipped with preset styles and color palettes so you can create complex, aesthetically pleasing charts with a few lines of code. It's designed to work with NumPy and pandas.) data structures and to support statistical tasks completed in SciPy and statsmodels.

Seaborn is built on top of Python's core visualization library matplotlib, but it's meant to serve as a complement, not a replacement. In most cases, you'll still use matplotlib for simple plotting, and you'll need a knowledge of matplotlib to tweak Seaborn's default plots.
