We are thrilled to announce Air, a new R formatter.

In 1973, statistician Francis Anscombe challenged the commonly held belief that “numerical calculations are exact, but graphs are rough” (Anscombe, 1973).

It’s perhaps the best argument for visualizing data. In this notebook we replicate his paper by using Plotnine to visualize those datasets and Polars to verify their descriptive statistics. More specifically, we:
