Making basic, good-looking plots in Python is tough. Matplotlib gives you great control, but at the expense of being very detailed. The rise of pandas has made Python the go-to language for data wrangling and munging but many people are still reluctant to leave R because of its outstanding data viz packages. ggplot is a port of the popular R package ggplot2. It provides a high level grammar that allow users to quickly and easily make good looking plots. So say good-bye to matplotlib, and hello to ggplot as your everyday Python plotting library!
