Familiarizing with disease data
The dataset containing disease cases from the World Health Organization (WHO) is loaded into your environment as the data frame who_disease.
In order to familiarize yourself with the data, let's start by printing it to the console.
Once you've investigated it a bit, make a simple bar chart of the number of observations by region using the supplied code. You will need to fill in the aes()thetics function to map the x-axis to the proper column name.
This course touches on a lot of concepts you may have forgotten, so if you ever need a quick refresher, download the Tidyverse Cheat Sheet and keep it handy!
