Use python and matplotlib to plot the frequency distribution of the “VesselType” column, and find the outliers. What you have to give me is the python source code. I will give you a subset of the CSV dataset. Your code will read from the CSV dataset, plot and find the outliers(you can set the parameters for the outliers by your own ). The total dataset will be more than a million rows. Your code will consider how to represent them and effectiveness.
