COVID Shiny App

Last updated on Nov 6, 2020
COVID-19
The US COVID Case Tracker App allows one to visualize the number of cases and deaths per State over time. California, Hawaii and Florida are selected by default but you can add or remove States using the selector box in the sidebar. The interactive maps use color to show the total cases and deaths per million people by State. Detailed information can be viewed by scrolling over the State of interest.
The data is from Johns Hopkins University and is updated daily. The app is hosted here on Shinyapps.io. You can also grab my code Github and run it on your own machine if you have R and RStudio installed.

Image of the reactive dashboard!

In this post, I’ve added a county-level case map and an animation that are not in the reactive dashboard.

Time Series Animation

This animated map shows the change in case count (per million people) over the first 12 months of the COVID-19 pandemic.

County Level Map

This map includes county level case counts. Scroll over the map to get detailed information on a specific county. Counties with missing data are shown in gray. Unlike the Shiny covid app, this post will only update when I compile the document (last updated on Thursday, July 08, 2021).

Let’s take a closer look at California.

The color package, Viridis, was used throughout this post to convey information with color. This color palette is designed to preserve information for viewers with common forms of color blindness. The code behind the maps and animation is available on Github.
