Biplots of Guerry data with data ellipses by region

Biplots (plots of variables: vectors and departments: points, in low-rank space), showing the relations among the variables (angles between vectors) and the locations of departments in relation to the variables and the biplot (principal component) dimensions.

The departments are color-coded by region of France
A data ellipse for each region is imposed on the plot to highlight the within-region location, scatter, and covariation.
