Today I learned a new #rstats package: #cartogram . This allows creation of Dorling cartograms (non-overlapping bubbles).

It's using the same 2020 presidential election county-level databased I created merging MIT Election Lab data with #tidycensus -derived files from the #census2020

The California Dorling plot is better by showing non-overlapping circles, especially in the Bay Area.

The Texas Dorling plot shows Harris County (Houston) nudged into the Gulf of Mexico. Dallas County and Travis County (Austin) have pushed (repelled) the little red bubbles to be more prominent.

All maps were created with the #tidyverse package #ggplot2

This is a lot of fun, for me, at least!
