This is an animated Choropleth map of Coronavirus cases in the USA. It shows confirmed cases per 100,000 habitants in each county. Darker red represents more cases. The timeline shows cases every week since January. Therefore this map will be updated with new data every week. It shows how the values cases have change between January and May 2020. The timeline only includes datapoints corresponding to every Wednesday of this year. Because the values have increased exponentially, the first color changes are observed in February and increase slowly at first but are widespread by March. The data includes case progression and population by county
I wanted to make an animated map that showed the changes and progression of the pandemic. This map also gives the opportunity to stop and hover over areas of interest and highlight for more information.
At first I made an animated dot map with data from CNN. Since then, the cases progressed so much it was more appropriate make a choropleth map. This data only includes cases assigned to a county. Some deaths are not included since they were assigned to each state.
Sources and Inspiration
The data on confirmed cases per county and population by county was obtained from USA FACTS. The shapefiles for the map where downloaded from ESRI. The colors were chosen from the Color Brewer. The code to make an animated choropleth map, was altered from rfdonohue's block.
At first I was underwhelmed with the data found on Coronavirus. I read criticism on different visualizations of COVD-19 cases and how it was displayed. I just wanted to show a map with the progression of the desease. I realized the best way to do it was with an animated choropleth map.
