In the opening chapter of this book, we’ll look at some examples of visualization throughout time and then we’ll talk about some of the different tools you might want to use to make visualizations. In chapter 2, we’re going to lay the foundation for the design concepts in this book by discussing how our brains perceive and organize information without our even realizing it. Finally in chapter 3, we’ll lay the foundation for the data-related concepts in this book by going over different data types and data structures you’ll encounter along your visualization journey.
