Using Mapbox GL JS
and a public data set
, we developed a map of the United States that displayed cumulative cases. We then moved to chart each coordinate to its relevant counties. We felt this was an appropriate amount of granularity — useful for all levels of government and for the everyday citizen. To not dismiss the importance of seeing state-by-state numbers, we also pulled U.S. state data to display on the left.
We next added properties to each county, noting the number of confirmed cases for each date. We used a publicly available GeoJSON boundary file of the U.S. counties and sourced case data from a UW GitHub repository, that outlines each case, date of confirmation and coordinates.
