Trend in COVID-19 cases by Zip code in Maryland

Since the Maryland Department of Health (MDH) started to display number of COVID-19 cases for each Zip code in its dashboard, I was wondering how to display this information in a nice way. The MDH display the information as a map – very nice but it lacks from where each Zip code came from: is the number of cases increasing or decreasing?

Following on my busy chart with the evolution of all Zip codes (and highlighting just one of them – that may not be the one you are interested in, see previous post), I created a simple dashboard where you can select the Zip code you are interested in and see how cases are evolving. You can play with it here: https://jepoirrier.shinyapps.io/md-coronavirus-zip-app/ (screenshot below). Enjoy!

As usual, the data is from the MDH coronavirus page. Please consult that page for official information. The data is in this file on the Github repo for my other project related to Coronavirus in Maryland.
