This video extends a previous video in which we used the collections Counter to determine the frequencies (number of occurrences) of letters in a particular poem. In this video we use the matplotlib -- a visualization library in Python -- to make nicer looking histograms than the terminal-level ones produced in the previous video. We prepare the data resulting from the collections counter to meet what was needed by matplotlib. First and foremost, it wanted two lists: one for the labels and one for the heights. We played a little more with colors, grids, and saving the plot to .png and .pdf formats.
