This article shows how to scrape, analyze and visualize movie data from IMDb. We will learn how to use Python and Pandas in order to collect, transform and present data in a beautiful way.


The second goal is to follow all steps in order to create popular DataIsBeautiful visualization:

So we will try to create similar artwork as the one posted on Reddit:

Open In Colab

And the game plan:


Step 1: Install Required Modules

In this tutorial we need 2 libraries:

import pandas as pd
from imdb import Cinemagoer

The library Cinemagoer can be installed by pip:

pip install cinemagoer

Cinemagoer (ex IMDbPY) is a Python package for retrieving the data of the IMDb movie database about movies, people and companies.

You can read more for this package here: cinemagoer.readthedocs

Step 2: Scrape IMDb Movie Data

Usually scraping or data collection is a tedious and hard process. Using Python libraries like Cinemagoer can make our life much easier.

So with a few lines of code we can extract well structured movie data from IMDb.

In this step you can find how to easily search and extract movie data from IMDb.

Get IMDb movie info

Let's start by collecting information about movies by using the IMDb identifier. So for the Game of Thrones - we get id - 3728462.

To extract director name we can use following code:

from imdb import Cinemagoer

# create an instance of the Cinemagoer class
ia = Cinemagoer()

# get a movie and print its director(s)
the_matrix = ia.get_movie('3728462')
for director in the_matrix['directors']:

which returns:

Michael Dixon

Search for movies

To search for IMDb movies using python we can use method: search_movie() and provide movie title:

# search for movie
movies = ia.search_movie('Game of Thrones')

the result is list of movies found from IMDb:

[<Movie id:0944947[http] title:_"Game of Thrones" (2011)_>,
 <Movie id:13380510[http] title:_Game of Thrones (2003) (V)_>,
 <Movie id:2231444[http] title:_Game of Thrones (2012) (VG)_>,
 <Movie id:11198330[http] title:_"House of the Dragon" (2022)_>,
 <Movie id:10090796[http] title:_Game of Thrones: The Last Watch (2019) (TV)_>,...

Extract IMDb series

In this step we will extract series and episodes for a given movie:

[<Movie id:0944947[http] title:_"Game of Thrones" (2011)_>,

by using the ID of the movie from the previous step:

series = ia.get_movie('0944947')

ia.update(series, 'episodes')

Collect episode data

Finally we will collect episodes and their data:

  • rating
  • votes
  • year
  • plot
import pandas as pd
from pandas import json_normalize

ep_data = []

ls = series.get('episodes')
for l in ls.values():
    for i in l.values():
#         print(i.movieID, '-',i.get('rating'), '-', i, )
        data =
        if 'episode of' in data.keys():
            data.pop('episode of')
        df_temp = pd.DataFrame.from_records([data])

df = pd.concat(ep_data)  

The result is DataFrame with data for all episodes from Game of Thrones:

title kind season episode rating votes original air date
0 Winter Is Coming episode 1 1 8.901235 49519 17 Apr. 2011
0 The Kingsroad episode 1 2 8.601235 37465 24 Apr. 2011
0 Lord Snow episode 1 3 8.501235 35445 1 May 2011
0 Cripples, Bastards, and Broken Things episode 1 4 8.601235 33707 8 May 2011
0 The Wolf and the Lion episode 1 5 9.001235 35046 15 May 2011

Step 3: Data Processing & Cleaning

In this step we would like to transform the original DataFrame data to Season vs Episode data.

For this purpose we will use pandas method pd.pivot_table():

pd.pivot_table(df, index='episode', columns='season', values='rating').round(1).fillna('').astype(str)

the result is table of episodes vs seasons information:

season 1 2 3 4 5 6 7 8
1 8.9 8.6 8.6 9.0 8.3 8.4 8.5 7.6
2 8.6 8.4 8.5 9.7 8.4 9.3 8.8 7.9
3 8.5 8.7 8.7 8.7 8.4 8.6 9.1 7.5
4 8.6 8.6 9.5 8.7 8.5 9.0 9.7 5.5
5 9.0 8.6 8.9 8.6 8.5 9.7 8.7 6.0
6 9.1 8.9 8.7 9.7 7.9 8.3 9.0 4.0
7 9.1 8.8 8.6 9.0 8.8 8.5 9.4
8 8.9 8.6 8.9 9.7 9.8 8.3
9 9.6 9.6 9.9 9.6 9.4 9.9
10 9.4 9.3 9.0 9.6 9.1 9.9

How the code above work:

  • we select the main parts of the pivot_table:
    • index='episode'
    • columns='season'
    • values='rating'
  • next we round up to 1 decimal point
  • replace NaN values by empty string

If you like to rename the column and index names we can use the following code:

df_p = pd.pivot_table(df, index='episode', columns='season', values='rating')

df_p = df_p.rename_axis('e')
df_p = df_p.rename_axis('s', axis=1)'GnBu', axis=None).format( precision=1, na_rep='')

Step 4: Visualize IMDb Data in Python

To make a beautiful heatmap from the IMDb data we can use Pandas Stylers - .style.background_gradient().

pd.pivot_table(df, index='episode', columns='season', values='rating').style.background_gradient(cmap='GnBu', axis=None).format( precision=1, na_rep='')

So this will produce heatmap from the series ratings:


To make it work we use:

  • axis=None - in order to apply the heat map over the whole DataFrame
    • we can apply it to rows - 0 or columns - 1
  • cmap='GnBu' - selecting the color styles. To view different options you can provide wrong value and check the error message - cmap='xxx'
  • precision=1 - control decimal points for the float numbers
  • na_rep='' - replace missing values by empty spaces

Step 5: Create Final Visualization

Finally we can do artwork by getting free images from: pixabay - golden dragon.

I'm using Inkscape to create the final image:

In this article, we saw how to scrape and transform IMDb data in order to produce popular visualization.

We covered different Python libraries and techniques for data collection, wrangling and presenting data.

A video with all steps will be published on the Youtube channel. Next we will cover how to create a more popular visualization.

If you have ideas for other visualizations from DataIsBeautiful or other places - please suggest them.

Happy visualizing!
