The best R package for learning to “think about visualization”

As a beginning data scientist, you’ll have quite a few subject areas that you need to learn (and eventually master). While you’ll certainly need to learn some math and statistics, math and stats are not the first things I recommend to most beginners.

Almost always, I recommend that people start with data visualization.

The reason for this, is that data visualization is so critical to almost every part of getting things done as a data scientist: reporting, analysis, exploratory analysis (e.g., EDA prior to machine learning). You need data visualization constantly. It’s necessary for nearly every data scientist at all levels.

If you’re a junior member of a data team, your core responsibilities may exclusively revolve around visualization (i.e., reporting, analysis, etc).
