The {geofacet} package allows to “arrange a sequence of plots of data for different geographical entities into a grid that strives to preserve some of the original geographical orientation of the entities”.
Like the previous post, it’s interesting if you view each entity as a unit and don’t care for its real size or weight, and don’t want to spend too much time manually finding the best grid.
We will again use the sameCOVID-19 dataset. We manually add the overseas départements once we have found the right grid (by trying different seeds) and adjust Corsica position.
