Activity 4: Generate a Bar Plot and a Heatmap to Represent Content Rating Types in the Google Play Store Apps Dataset

Solution

1. Load the necessary Python modules and download the dataset hosted in the book GitHub repository and format it as a pandas DataFrame:

   # load pandas library
   Import pandas as pd
   # download file 'googleplaystore.csv' from course GitHub repository
   # read the dataset as a pandas DataFrame
   gps_apps_df =pd.read_csv('https://raw.githubusercontent.com/TrainingByPackt/Interactive-Data-Visualization-with-Python/master/datasets/googleplaystore.csv')
   #worldrank_df = pd.read_csv('https://raw.githubusercontent.com/TrainingByPackt/Interactive-Data-Visualization-with-Python/master/datasets/googleplaystore.csv')
   # preview DataFrame
   gps_apps_df.head()

   The output is as follows:
