Nuclear bombs per country
You've been given a version of the Nuclear Explosion DataBase (NEDB) where country names are specified in the column headers (nuke_df). You want to visualize how many nukes were detonated per year per country. You'll need to pivot the data and replace NA values first.
The ggplot2 package has been pre-loaded for you.
