For the same dataframe data build a horizontal bar chart representing the average monthly rainfall level for New Delhi and Madurai. Follow the next steps:

1. Initialize horizontal bar chart for the new_delhi data. Use values of the 'Month' column as the first parameter and values of the 'Rainfall' column as the second one.
2. Initialize horizontal bar chart for the madurai data and place it to the right of previously built data (new_delhi). Set label parameter to 'Madurai'.
