use of value_counts()
Here is what the above code is Doing:
1. We’re using the value_counts() method to count the number of times each value appears in the column.
2. We’re using the .head() method to return the first 5 rows of the result.
3. We’re using the .sort_values() method to sort the values by the number of times they appear.
4. We’re using the .plot() method to plot the results as a bar chart.
