Creating fundamental charts

Tableau provides you with the flexibility to create a wide range of almost limitless charts, limited only by your creativity and advanced mathematics skills. Fortunately, the charts you will learn about for the Tableau Desktop Specialist Exam do not require you to implement trigonometry, geometry, or calculus. In my 10 years of professional experience with the tool, these charts cover well over 90% of use cases.
