Check out this ChartFactor application, which allows users to visualize the National Center for Health Statistics (NCHS) drug poisoning mortality rates by county. Using a time slider we can replay and explore the data over time. A tab on the right side can be used to open a trend chart which allows users to compare county trends amongst the various counties on the map. Below this, there is also a tab which allows users to generate a heat map for the top 20 counties by drug poisoning mortality across a range of years.
You can access this web app live at https://chartfactor.com/NCHS-drug-poisoning-app/. We created it using our ChartFactor Studio software and made sure to give it our own special look and feel as well!
Data provided by the NCHS and available at https://data.cdc.gov/NCHS/NCHS-Drug-Poisoning-Mortality-by-County-United-Sta/rpvx-m2md
For our Data engine we used OpenSearch whilst the base map tiles were provided by OpenStreetMap.
