Python: I am am having issues plotting graphs in notebook even after using matplotlib…What am i not doing right? [migrated]

I am new to cybersecurity. Doing a virtual internship on forage and I have been having issues in completing some of the questions. I will try to list them one after the other.

I used import pandas as pd and import matplotlib.pyplot as plt though I have been able to write code to execute some of the questions asked but I will list below some of the questions I have not been able to answer.

1. Return a dataframe that contains the number of distinct destinations that each source has interacted with to, sorted in descending order.
2. Transaction types bar chart, Transaction types split by fraud bar chart.(where types and fraud are columns in the data file.)
