Chapter 5: Data Visualization

Being able to visualize data is the backbone of data analysis. The area of data visualization is very exciting, as there are endless possibilities for novelty and creativity in drawing visualizations that tell better stories about your data. However, the core mechanisms of even the most innovative graphs are similar. In this chapter, we will cover these fundamental mechanisms of visualizations that give life to the data and allow us to compare, analyze, and see patterns in it.

As you will learn these fundamental mechanisms, you will also be developing a better backbone/skillset for your data preprocessing goals. If you can fully understand the connection between the data and its visualizations, you will be more effective at preprocessing data for effective visuals. In this chapter, you will work with the data that I have already preprocessed, but in later chapters, we will cover the concepts and techniques that lead to these preprocessed datasets.
