You are given the same dataframe data. Your tasks are:

1. Save data for 'MADURAI' in the madurai variable.

2. Call .bar() function twice:

   • the first time to build bars for the new_delhi data (the 'Month' column on the x-axis and the 'Rainfall' column on the y-axis);
   • the second time to build bars for the madurai data above built ones (the same columns and order as for the new_delhi data).

   Use 'New Delhi' and 'Madurai' as the label parameters.

3. Display the legend of the plot.
