In this article, I will show by example how to approach data visualization using the concepts of The Grammar of Graphics. The goal is to provide a structured and reusable way of thinking that supports getting from the chart in your mind’s eye to the chart on the screen.

In addition, I provide this notebook that contains 30 challenges, with increasing difficulty, to help you test your new data visualization knowledge. The notebook runs in the cloud so it’s ready to use immediately (no installation or setup required).
