Activity 13: Visualizing the Titanic Dataset Using a Pie Chart and Bar Plots

Solution

1. Import all the lines from the csv file in the titanic_train.csv dataset file and store it in a list:

   import csv
   lines = []
   with open('titanic_train.csv') as csv_file:
       csv_reader = csv.reader(csv_file, delimiter=',')
       for line in csv_reader:
           lines.append(line)

2. Generate a collection of passengers objects. This step is designed to facilitate the subsequent steps where we need to extract values of different properties into a list for generating charts:

   data = lines[1:]
   passengers = []
   headers = lines[0]

3. Create a simple for loop for the d variable in data, which will store the values in a list:

   for d in data:
       p = {}
       for i in range(0,len(headers)):
        &...
