Working with geom_col

In ggplot, there are two different ways to make bar plots: geom_col() and geom_bar().

If your data is in the form where the height of the bar is encoded in a column that you want to map to the y-axis, like counts of diseases are in our data, you want to use the geom_col() option.

Let's make a barplot of the number of cases recorded by disease for India in 1980 using geom_col().
