Introduction

type: prompt

To satisfy the requirements of the Coursera Developing Data Products Course, the 9th course in the JHU Data Science Specialization Certification, an interactive Shiny application was built.

The Shiny application demonstrates how State COVID-19 data can be viewed in different manners.

This presentation introduces you to the application and how it works.

What to Expect

type: prompt

The default view shows the COVID19 case history of the Alaska from January 2020 to December 2021

  • The user can select a different dataset for six states:
    • Alaska (fewer people, fewer cases)
    • Colorado (I live here)
    • Georgia (my mother lives there)
    • Florida (a lot of retirees live there)
    • Missouri (my daughter live there)
    • New York (more people, more cases)

Default View

  • Any change the user makes will be immediately reflected.
