Adventures of a self-learning data scientist - Update: IMF World Economic Outlook Database, April 2021

I have updated my Shiny app every half a year since April 2019. So this is the fifth iteration. And I believe I could make it more usable this time, as I made some improvements so that:

You can select multiple areas.
You can see the values by hovering over a chart.
You can compare the current forecast with the previous one.
You can download data as a csv file.

Under the hood, I reconstructed the app as a R package. I could do all of these, as I read the book “Mastering Shiny” by Hadley Wickham. Thank you, Hadley.
