A COVID Small Multiple

27 March 2020 John Burn-Murdoch has been doing very good work at the Financial Times producing various visualizations of the progress of COVID-19. One of his recent images is a small-multiple plot of cases by country, showing the trajectory of the outbreak for a large number of countries, with a the background of each small-multiple panel also showing (in grey) the trajectory of every other country for comparison. It’s a useful technique. In this example, I’ll draw a version of it in R and ggplot.

Animating U.S. Population Distributions

14 March 2020 With the 2020 U.S. Census in motion already, I’ve been looking at various pieces of data from the Census Bureau. I decided I wanted to draw some population pyramids for the U.S. over as long a time series as I could. What’s needed for that are tables for, say, as many years as possible that show the number of males and females alive at every year of age from zero to the highest age you’re willing to track.
