Dorling Cartogram (packed circles)

Inspired by this post:

        

I was able to use the cartogram package to create what is called a “dorling cartogram”

Here is:

• the code used to generate the bubbles

• Geospatial files with the circle radius proportional to the population (2015 census)
  • Rds file - sf polygons of circles
  • geojson files - the circles plus normal state and county polygons. Including these as Alaska & Hawaii moved to the lower left. These come from urbnmapr
  • csv of circle centroids and population sizes

• What it looks like with ggplot2

      

• And with tmap
