Smoothing

To practice on the remaining layers (statistics, coordinates and facets), we'll continue working on several datasets from the first course.

The mtcars dataset contains information for 32 cars from Motor Trends magazine from 1974. This dataset is small, intuitive, and contains a variety of continuous and categorical (both nominal and ordinal) variables.

In the previous course you learned how to effectively use some basic geometries, such as point, bar and line. In the first chapter of this course you'll explore statistics associated with specific geoms, for example, smoothing and lines.
