A video tour of the visualization is available on youtube.
All of the data used in to develop the plots and maps in this project are available at www.evl.uic.edu/aej/424/18p1data.zip
The data includes:
Example of geographic distribution of cholera deaths
How to run the code locally:
The following libraries are necessary to run this visualization: shiny, shinydashboard, ggplot2, DT, jpeg, leaflet, reshape, rgdal, RColorBrewer and ggrepel
Example of a dashboard tab
