This repo contains 3 builds of a Plotly app in R for quantifying covid-related mortality.

It also contains a Dockerfile for deploying local and remote environments.

These apps parse a large csv (~50MB) from the CDC: https://data.cdc.gov/NCHS/Weekly-counts-of-death-by-jurisdiction-and-cause-o/u6jv-9ijr/

• sample.R displays weekly mortality by for one cause, state, and year
• sample_withloop.R -- by multiple years for one cause and state
• sample_loop_plus_selector.R -- by multiple years with state, cause, & count type selectors

• Docker Desktop
• git
• heroku-cli
• A Heroku account
