On this year-long “Month to Master” challenge, for the month of February, I set out to build on January’s progress to build an R-based visualization using Shiny.

Ultimately, I plan to build an interactive visualization that uses voter file political data. This achieves multiple objectives:

• Builds on my polling and Shiny courses from January.
• Allows me to explore data in an area of interest.
• Easy to download data.
• Use case for dashboard to have sliders.

Here we go.
