covid-19 dashboard

The repo contains code references and materials used in a 10-part tutorial series on developing a real-time analytics app to monitor the covid-19 (coronavirus) situation, and in the process learn about:

  • Data visualization in base R
  • Data visualization using ggplot2
  • Cleaning and transforming data using tidyverse libraries: dplyr, tidyr etc
  • Web app / dashboard development using shiny

Build and deploy a real-time analytics dashboard (optionally with your custom sub-domain, for free) with this multi-part lesson. The course will walk you through the process of cleaning data, creating highly compelling data visualizations, and then combining them with a web app framework that is pleasant and visually appealing.

By the end of this course, you will have a web dashboard that is deployed and accessible on the web by anyone, on any devices (responsive web design).

Learning Outcomes

  • Learn to develop a modern, reactive web application using R and the Shiny Web App framework
  • Learn to use one of the most popular, powerful data visualization library (ggplot) to create compelling visuals on the web
  • Learn to take advantage of modern web development practices such as Bootstrap 4, responsive web design, and UX thinking
  • Learn how a framework like Shiny allows you to author your application by transforming your R code into HTML, CSS and JavaScript.
  • Learners are expected to develop their own dashboard, and deploy to the free shinyapps.io hosting service.
