Plotting stop length
If you were stopped for a particular violation, how long might you expect to be detained?
In this exercise, you'll visualize the average length of time drivers are stopped for each type of violation. Rather than using the violation column in this exercise, you'll use violation_raw since it contains more detailed descriptions of the violations.

Instructions
- For each value in the
riDataFrame'sviolation_rawcolumn, calculate the mean number ofstop_minutesthat a driver is detained. - Save the resulting Series as a new object,
stop_length. - Sort
stop_lengthby its values, and then visualize it using a horizontal bar plot. - Display the plot.
