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)):
         &...
