Introduction

The Python Package Index contains libraries for almost every data visualization requirement, from Pastalog for real-time visualizations of neural network training to Gaze Parser for eye movement research. Some of these libraries are used in a variety of fields. Despite this, many of them are intensely focused on completing a specific task.

Here’s a rundown of 11 interdisciplinary Python data visualization libraries that you’ll learn about in this post, from most popular to least popular. Continue reading to learn how to use Data Visualization Tool and Python data visualization libraries to create data visualization charts.

What is a Python Data Visualization Library?

A Python data visualization library is a tool that transforms raw data into visual representations like charts and graphs, aiding in easier comprehension of complex information. It bridges data and insights, enabling users to uncover trends, patterns, and relationships.

These libraries offer diverse functions and methods to create various visualizations, catering to different data types and analysis needs. Python data visualization libraries provide flexibility and versatility, from simple line charts to sophisticated heatmaps. By democratizing data analysis, they empower users of all levels to make informed decisions without requiring extensive technical skills.

Top Python Data Visualization Libraries in 2024

Python data visualization scene boasts an array of top-tier libraries catering to diverse needs. Each of Python data visualization libraries has a distinct style, making them stand out. Let’s hop onto the article and learn about different libraries in detail:

Matplotlib

Matplotlib Python Library is used to generate simple yet powerful visualizations. It is more than a decade old and the most widely used library for plotting in the Python community. Matplotlib can plot a wide range of graphs – from histograms to heat plots.

Matplotlob is the first Python data visualization library. Therefore, many other libraries are built on top of Matplotlib and designed to work with the analysis. Python data visualization libraries like pandas and matplotlib are “wrappers” over Matplotlib, allowing access to several Matplotlib methods with less code.

Matplotlib’s versatility allows for visualization types such as:

• Scatter plots
• Bar charts and Histograms
• Line plots
• Pie charts
• Stem plots
• Contour plots
• Quiver plots
• Spectrograms

You can create grids, labels, legends, etc., with ease since everything is easily customizable.

Seaborn

Seaborn is a popular data visualization library built on top of Matplotlib. Seaborn’s default styles and color palettes are much more sophisticated than Matplotlib. Seaborn puts visualization at the core of understanding any data. Seaborn is a higher-level library- it’s easier to generate specific plots, including heat maps, time series, and violin plots.

ggplot

ggplot is one of the popular data visualization Python libraries based on R’s ggplot2 and the Grammar of Graphics. You can construct plots using high-level grammar without worrying about the implementation details. ggplot operates differently compared to Matplotlib: it lets users layer components to create a complete plot. For example, the user can start with axes and add points, a line, a trend line, etc. The Grammar of Graphics has been hailed as an “intuitive” method for plotting. However, seasoned Matplotlib users might need time to adjust to this new mindset.

Bokeh

Bokeh, native to Python, is also based on The Grammar of Graphics like ggplot. It also supports streaming and real-time data. The unique selling proposition is its ability to create interactive, web-ready plots, accessible output as JSON objects, HTML documents, or interactive web applications.

Bokeh has three interfaces with varying degrees of control to accommodate different types of users. The topmost level is for creating charts quickly. It includes methods for building common charts such as bar plots, box plots, and histograms. The middle level allows the user to control the basic building blocks of each chart (for example, the dots in a scatter plot) and has the same specificity as Matplotlib. The bottom level is geared toward developers and software engineers. It has no pre-set defaults and requires the user to define every element of the chart.

Plotly

While Plotly is widely known as an online data visualization libraries, very few people know it is accessible from a Python notebook. Like Bokeh, Plotly’s strength lies in making interactive plots, and it offers contour plots, which are not found in most libraries.

Pygal

Pygal, like Plotly and Bokeh, offers interactive plots that you can embed in a web browser. The ability to output charts as SVGs is its prime differentiator. For work involving smaller datasets, SVGs will do just fine. However, charts with hundreds of thousands of data points become sluggish and have trouble rendering.

It’s easy to create a nice-looking chart with just a few lines of code since each chart type is packaged into a method and the built-in styles are great.

Altair

Altair is one of the declarative statistical python libraries for data visualization based on Vega-Lite. You only need to mention the links between data columns to the encoding channels, such as x-axis, y-axis, color, etc. The rest of the plotting details are handled automatically. This fact makes Altair simple, friendly, and consistent. It is easy to design compelling and beautiful visualizations with a minimal amount of code using Altair.

Geoplotlib

Geoplotlib is a toolbox used for plotting geographical data and map creation. It can create a variety of map types, like choropleths, heatmaps, and dot-density maps. Pyglet (an object-oriented programming interface) is required to use Geoplotlib.

Geoplotlib reduces the complexity of designing visualizations by providing a set of in-built tools for the most common tasks such as density visualization, spatial graphs, and shapefiles.

Since most Python data visualization libraries don’t offer maps, it’s good to have a library dedicated to them.

Gleam

R’s Shiny package is the inspiration behind Gleam. It allows the user to turn any analysis into interactive web apps using only Python scripts. Gleam users don’t need to know HTML, CSS, or JavaScript to do this. Gleam works with any Python data visualization library. Once users have created a plot, they can build fields on top of it to filter and sort data.

Missingno

Dealing with missing data is cumbersome. Missingno can quickly gauge the completeness of a dataset rather than painstakingly searching through a table. The user can filter and sort data based on completion or spot correlations with a heat map or a dendrogram.

Leather

Leather is designed to work with all data types and produces charts such as SVGs. It is scalable without losing image quality. Leather’s creator, Christopher Groskopf, puts it best: “Leather is the Python charting library for those who need charts now and don’t care if they’re perfect.”

Since this library is relatively new, some of the documentation is still in progress. The charts are pretty basic—but that’s the intention.

There is a wide range of visualization tools, with huge diversity, depending on the focus of the task at hand available for Python. The sheer number of libraries available reflects this fact. It is imperative for the users to bear in mind the differences between the approaches and their implications before zeroing in on a particular approach.

Tips for Choosing the Right Python Data Visualization Library

Choosing the ideal data visualization tool can feel overwhelming. With so many options available, how do you pick the one that best suits your needs? Well, to help you with this, here are several tips you must consider:

Types of visualizations

Check if the tool supports the types of charts and plots you need for your data. Ensure the tool offers a variety of chart options to meet your needs. Different visualization tools may excel at different types of charts, so choose accordingly.

Input Formats

While looking for the ideal Python data visualization libraries, ensure they can handle the input data formats you use. It should support standard formats like CSV, JSON, and Excel files.

Output Formats

Think about the output formats you’ll need for sharing or embedding visualizations. Choose a tool that offers flexibility in output formats to meet your sharing requirements. Prefer tools that allow you to export visualizations to various file formats or offer sharing options for web-based visualizations.

Compatibility with Existing Tools

Evaluate how well the tool integrates with your current data analysis and manipulation tools. Seamless integration can streamline your workflow and improve efficiency. Consider tools that complement your existing toolkit.
