Data visualization, What, Why, and How

This is the first lesson of the Data Visualization Beyond the Tutorial course.

In this unit, we will ask seemingly simple questions: what, why and how. This unit will allow us: me, the teacher and you, the students, to set up a common language, and to understand what this course is about. You will also see some interesting examples and use cases.

We will start with the “what”, by seeing some motivational examples; continue to the “why” data visualization works; switch to the question of “what is the right approach” and finally, will end up with a quick overview of the “how” — how to produce good and effective data visuals.
