How to Display Rich Media Contents (Image, Audio, Video, etc) in Jupyter Notebook?¶
Jupyter notebook and Lab have become a favorite tool for data scientists and developers all over the world to perform data analysis and related tasks.
> Why Jupyter Notebooks are Famous? Why Jupyter Notebooks are Preferred tool by Data Scientists Worldwide?¶
Its user-friendly interface and out-of-box functionalities like supporting shell commands from the notebook make it a unique and go-to tool in the data science community.
The jupyter notebook is based on the IPython kernel running under the hood. IPython kernel is just like a normal python interpreter but with lots of additional functionalities.
As Jupyter notebook is used by the majority of data scientists worldwide, it supports displaying rich media contents (image, markdown, latex, video, audio, HTML, etc.). This frees users from the hassle of using different tools to see contents of different types. We can play audio and video in notebook which is displayed.
It even let us include static and interactive charts in notebooks that are created during analysis. It even let us create dashboards (voila).
All pieces of analysis are available in one place. This makes reproducible research easy to conduct.
It is also very useful for presentation purposes as many people use Jupyter Notebooks for presentations as well.
All these benefits make Jupyter notebooks the most preferred tool by data scientists worldwide.

1. Important Classes and Functions of "IPython.display" Module ¶
Below is a list of classes and methods available with the IPython.display module.
Classes¶
The classes displayed below accept data of a particular type and when executed from the jupyter notebook cell will display the content of that type in a notebook.
- Audio
- Code
- FileLink
- FileLinks
- HTML
- IFrame
- Image
- SVG
- JSON
- JavaScript
- Markdown
- Latex
- ScribdDocument
- Pretty
- Video
- YouTubeVideo
- VimeoVideo
Functions¶
The "display_*()" functions can take as input many objects created using classes mentioned above and display all of them one after another. The method as per their name takes objects of one kind as input except for the last display() method which can combine contents of different types and display them.
- display_html()
- display_jpeg()
- display_png()
- display_svg()
- display_json()
- display_javascript()
- display_markdown()
- display_latex()
- display_pretty()
- display()
This ends small introduction and now let's start with coding part. We'll start by importing the display module.
from IPython import display
2. How to Display "Audio" or "Sound" Player in Jupyter Notebook? ¶
The Audio class let us display audio files in a jupyter notebook. It provides us with a simple player that we can pause/play to listen to the audio. The first argument of the method is data which accepts one of the below inputs and generates an Audio object which when displayed will display a small player that can play audio.
- numpy array (1d or 2d) of a waveform
- list of floats containing waveform
- local audio filename
- URL
Below we have given as input URL of an audio file and it'll display an audio object which can play that audio. We have also explained below with examples of how we can play audio from local files. We can also set the autoplay parameter to True and it'll start playing audio immediately. It has another important parameter named rate which specifies sampling rate and should be used if data is provided as a numpy array or list of floats.
When we give an object created by any class as the last line in the notebook cell, it'll display an object of that type.
Please make a note that the majority of classes available from the display module provides boolean parameter named embed which if set to True will put DATA URI of the content into a notebook and next time we won't need to load that content into the notebook from file/URL.
display.Audio(url="https://file-examples-com.github.io/uploads/2017/11/file_example_MP3_700KB.mp3")
display.Audio(filename="sample_audio.mp3")
display.Audio(data="sample_wav.wav")
display.Audio(data="sample_wav.wav", autoplay=True)
3. How to Display "Code" in Jupyter Notebook? ¶
The Code class can be used to display code in syntax-highlighted format. We can provide code information to the class in one of the below-mentioned ways.
- String of code
- Local filename
- URL where the file resides
Below we have explained with simple examples of how we can use this class.
display.Code("profiling_examples/example1_modified.py")
display.Code(filename = "sample.js")
4. How to Display File as Downloadable Link using "FileLink" in Jupyter Notebook? ¶
The FileLink class lets us create links around files on local. It accepts a file name as input and will create a link around it. We can give prefix and suffix to use around link using result_html_prefix and result_html_suffix commands.
We have explained the usage of the class below with simple examples. This can be useful when we are running a notebook on platforms like kaggle or google collab or any other platform where we don't have access to local disks to download files which might be generated during our analysis like model weights file, plotting files, etc.
display.FileLink(path="profiling_examples/example1_modified.py")
display.FileLink(path="profiling_examples/example1_modified.py", result_html_prefix="Profiling Examples : ")
display.FileLink(path="profiling_examples/example1_modified.py", result_html_prefix="Profiling Examples : ", result_html_suffix=" Sample Profiling File")
5. How to Display All Files in Directory as Downloadable Links using "FileLinks" in Jupyter Notebook? ¶
The FileLinks class works exactly like the FileLink class with the only difference that it accepts directory names as input and creates a list of links for all the files present in it.
Below we have explained the usage of the same on a temporary folder named sample_files which we created for this. It also provides a boolean parameter named recursive which is True by default and recurses in all subdirectories to display files in all of them. We can set this parameter to False if we don't want links of subdirectories.
display.FileLinks(path="sample_files")
display.FileLinks(path="sample_files", result_html_prefix="Sample Text Files : ", recursive=False)
display.FileLinks(path="sample_files", result_html_prefix="Sample Files : ", recursive=True)
6. How to Display "HTML" in Jupyter Notebook? ¶
The HTML class let us display HTML in notebook. The class accepts a list of the below-mentioned data types as input to create an HTML object.
- String containing HTML code
- URL
- HTML File on local system
Below we have explained the usage of the class with simple examples. We have also created a sample HTML file from one of our blogs and displayed it as a sample.
sample_html = '<html><body><h3>Hello World</h3><h4>Hello World</h4><h5>Hello World</h5><h6>Hello World</h6></body></html>'
display.HTML(data=sample_html)
display.HTML(url="https://google.com")
display.HTML(filename="basic-principles-of-information-visualization.html")
Basic Principles of Information Visualization¶
We'll be discussing the basic principles of visualizing data that you have collected and analyzed. We'll be talking about various principles to keep in mind when forming visualization which makes sense to the human brain. Our main focus during this blog will be to learn about ways that help present data that is intuitive to the human brain and can be very easily interpreted without any kind of training.
Data Visualization¶
Data visualization is divided into 3 categories:
- Information Visualization: It typically refers to abstract information that may not have a position in space like line chart representing stock price over years.
Examples: static plots using matplotlib, seaborn, etc. - Scientific Visualization: It typically refers to representing data that has a physical representation in space like sonography report, methane distribution in combustion engine, CT Scan report, MRI scan report where each data point has an actual 3D location in space.
- Visual Analytics: It typically refers to interactive dashboards/visualizations and statistical algorithms that one can analyze from a different aspect.
Examples: dashboards using dash, plotly, bokeh, voila, panel, etc
"display_html()"¶
The display_html() method takes as input list of HTML object created using display.HTML class and displays all of them one after another in jupyter notebook. Below we have explained the usage with a simple example where we combine HTML of google URL and local file.
html1 = display.HTML(url="https://google.com")
html2 = display.HTML(filename="basic-principles-of-information-visualization.html")
display.display_html(html1, html2)
7. How to Display "IFrame" in Jupyter Notebook? ¶
The IFrame class lets us display iframes in jupyter notebooks. It lets us also specify the width and height of the iframe. Below we have used an iframe to display local HTML files and IPython docs using URL.

display.IFrame(src="https://ipython.readthedocs.io/en/stable/api/generated/IPython.display.html", width=500, height=600)
8. How to Display "Images" in Jupyter Notebook? ¶
The Image class let us display image of type jpg/jpeg/png/gif in jupyter notebook. We can give either image information as str/bytes or filename/URL. Below we have explained with a few simple examples of how we can display images of different types loaded from local file and URL.
display.Image("cc2.png", height=150, width=150)
display.Image("https://storage.googleapis.com/coderzcolumn/static/blogs/home/home_main.jpg")
img_data = open("cc2.png", "rb").read()
display.Image(data=bytearray(img_data), height=150, width=150)
display_jpeg()¶
The display_jpeg() method takes as input image objects of jpeg/jpg files created using the Image class and display images one after another in a notebook.
img2 = display.Image("https://storage.googleapis.com/coderzcolumn/static/blogs/home/home_main.jpg")
display.display_jpeg(img2)
display_png()¶
The display_png() method works like the display_jpeg() method and takes as input a list of image objects containing information about the list of png files.
img1 = display.Image("cc2.png", height=150, width=150)
display.display_png(img1)
9. How to Display "SVG Images" in Jupyter Notebook? ¶
The SVG class lets us display the SVG images in a jupyter notebook. We can provide the file name of the image on a local system or web URL to display the SVG image.

display_svg()¶
The display_svg() image takes as an input list of SVG objects created using the SVG class and displays them one after another.
img = display.SVG("supervised_workflow.svg")
display.display_svg(img)
10. How to Display "JSON" in Jupyter Notebook? ¶
The JSON class displays contents of json as a directory-like structure in jupyter notebook which we can explore by expanding/collapsing node of structure. We need to give json dictionary as input to the method and it'll display contents in a tree-like interactive structure. The class can load JSON from the local files as well as URLs on the web.
Please make a note that this functionality only works with Jupyter lab. It does not work in a jupyter notebook at the time of writing this article.
json_data = [{ "Name": "William", "Employee ID" : 1, "Address": "New York"}]
display.JSON(data=json_data)
display.JSON(data=json_data, expanded=True)
display_json()¶
The display_json() method takes as input a bunch of json objects created using JSON class and displays all of them one after another.
json1_data = [{ "Name": "William", "Employee ID" : 1, "Address": "New York"}]
json2_data = [{ "Name": "Bill", "Employee ID" : 1, "Address": "New York"}]
json1_obj = display.JSON(json1_data, expanded=True)
json2_obj = display.JSON(json2_data, expanded=True)
display.display_json(json1_obj, json2_obj)
11. How to Display "Javascript" in Jupyter Notebook? ¶
The Javascript class lets us execute javascript code in jupyter notebook. We can provide the file name or URL of javascript code and it'll execute it. We can access the HTML element of cell output using the element variable in javascript and modify it according to our need to display the output of script execution in the cell output of the notebook. Below we have executed a simple javascript that compares three numbers and prints the largest number as cell output by setting the innerHTML attribute of element.
Please make a note that this functionality only works with Jupyter lab. It does not work in a jupyter notebook at the time of writing this article.
sample.js
// program to find the largest among three numbers
// take input from the user
const num1 = 12
const num2 = 10
const num3 = 35
let largest;
// check the condition
if(num1 >= num2 && num1 >= num3) {
largest = num1;
}
else if (num2 >= num1 && num2 >= num3) {
largest = num2;
}
else {
largest = num3;
}
// display the result
element.innerHTML = '<h1>Hello World</h1>'
display.Javascript(filename="sample.js")
display_javascript()¶
The display_javascript() method takes as input list of objects created using Javascript class and executes all of them one after another.
jscript1 = display.Javascript(filename="sample.js")
display.display_javascript(jscript1)
