Bar chart

Bar charts visualize data that is organized according to categories as a series of bars, where the height of each bar represents the values of the data in this category.

For example, in this exercise, you will visualize the number of gold medals won by each country in the provided medals DataFrame. The DataFrame contains the countries as the index, and a column called "Gold" that contains the number of gold medals won by each country, according to their rows.

Call the ax.bar method to plot the "Gold" column as a function of the country.
Use the ax.set_xticklabels to set the x-axis tick labels to be the country names.
In the call to ax.set_xticklabels rotate the x-axis tick labels by 90 degrees by using the rotation key-word argument.
Set the y-axis label to "Number of medals".
