Humans are visual creatures and have evolved to be able to quickly notice the meaning when information is presented in certain ways that cause the wiring in our brains to have the light bulb of insight turn on. This "aha" can often be performed very quickly, given the correct tools, instead of through tedious numerical analysis.

Tools for data analysis, such as pandas, take advantage of being able to quickly and iteratively provide the user to take data, process it, and quickly visualize the meaning. Often, much of what you will do with pandas is massaging your data to be able to visualize it in one or more visual patterns, in an attempt to get to "aha" by simply glancing at the visual representation of the information.

This chapter will cover common patterns in visualizing data with pandas. It is not meant to be exhaustive in coverage. The goal is to give you the required knowledge to create beautiful data visualizations on pandas data quickly and with very few lines...
