So far, we've mostly worked with plots that are quick to analyze and make sense of. Line charts, scatter plots, and bar plots allow us to convey a few nuggets of insights to the reader. We've also explored how we can combine those plots in interesting ways to convey deeper insights and continue to extend the storytelling power of data visualization. In this lesson, we'll explore how to quickly create multiple plots that are subsetted using one or more conditions.

We'll be working with the Seaborn visualization library, which is built on top of matplotlib. Seaborn has good support for more complex plots, attractive default styles, and integrates well with the pandas library.

As we learn Seaborn, we'll be working with a data set of the passengers from the Titanic. The Titanic shipwreck is the most famous shipwreck in history and led to the creation of better safety regulations for ships. One substantial safety issue was that there were not enough lifeboats for every passenger on board, which meant that some passengers were prioritized over others to use the lifeboats.

The data set was compiled by Kaggle for their introductory data science competition, called Titanic: Machine Learning from Disaster. The goal of the competition is to build machine learning models that can predict if a passenger survives from their attributes. While this lesson doesn't explicitly cover machine learning, you can learn about the fundamentals of machine learning in our Machine Learning Fundamentals course and learn more about Kaggle in our Kaggle Fundamentals course.
