Netflix! What started in 1997 as a DVD rental service has since exploded into one of the largest entertainment and media companies.
Given the large number of movies and series available on the platform, it is a perfect opportunity to flex your exploratory data analysis skills and dive into the entertainment industry. Our friend has also been brushing up on their Python skills and has taken a first crack at a CSV file containing Netflix data. They believe that the average duration of movies has been declining. Using your friends initial research, you'll delve into the Netflix data to see if you can determine whether movie lengths are actually getting shorter and explain some of the contributing factors, if any.
You have been supplied with the dataset netflix_data.csv , along with the following table detailing the column names and descriptions:
The data
netflix_data.csv
| Column | Description |

show_id | The ID of the show |
type | Type of show |

# Load the CSV file and store as netflix_df
netflix_df = pd.read_csv('netflix_data.csv')
# Filter the data to remove TV shows and store as netflix_subset
netflix_subset = netflix_df[netflix_df['type'] == 'Movie']
# Keep only the required columns in netflix_movies
netflix_movies = netflix_subset[['title', 'country', 'genre', 'release_year', 'duration']]
# Filter netflix_movies to find movies shorter than 60 minutes
short_movies = netflix_movies[netflix_movies['duration'] < 60]
# Create a list to store colors based on genre
colors = []
for index, row in netflix_movies.iterrows():
genre = row['genre']

# Initialize a figure object

# Create a scatter plot for movie duration by release year
ax.scatter(netflix_movies['release_year'], netflix_movies['duration'], c=colors)
# Set labels and title
