To get the most out of this book
Basic knowledge of Tableau will be an advantage and you will need a Tableau license after your 14-day free trial ends. You will also benefit from basic knowledge of R or Python if you wish to get the most out of Chapter 15, Integrating Programming Languages. You can, however, also follow along with the steps and learn as you go.
Other helpful installations will be mentioned in the book as needed, all in the realm of the average free-ware installation on Windows or Mac.
