Parsing Apple’s COVID mobility data
Friend of the site Kieran Healy, a sociology professor at Duke and author of Data Visualization: A Practical Introduction, has taken the mobility data released by Apple in connection with the COVID-19 pandemic and parsed it in a few different ways.
If you’d like to see what goes into taking a big data set and generating charts that are readable and informative, Healy’s post—complete with plenty of R code—is the one for you. I particularly enjoyed his work on removing weekly seasonality from the data and his legwork finding explanations for certain aberrations in the data sets.
