Find the top frequently used words in the book "Sense and Sensibility". The book is in the sense_andsensibility.txt file. The words should not be case sensitive, meaning "Mother" and "Mother" are considered the same word. Replace all the punctuation marks with a space. Use the "stopwords.txt" file to remove all the stop words in the text. (Do NOT modify the stopwords.txt file)  The diagram should contain the ranking, the top 30 words, and the number of times they appeared in the book. The number of stars will be the number of appearances divided by 10. For example, "mother" appears 263 times; there are 26 stars displayed.
