Python is one of the most preferred programming languages for data science and data Visualization needs. Dada visualization refers to the discipline of visually representing data through formats like graphs, images, plots and other such forms. Afterall visual representation of complex and huge datasets is much easier to understand, analyse, identify patterns and get other important business centric insights rather than going through thousands of excel files.

Python Visualization Libraries to use in 2023

Most common mistake clients make when searching for the best Python visualization Library for their project is searching for “most popular python data visualization library” or “most used python data visualization library”.

Such keywords will give you a list of the top trending tools and libraries, however its relevance to your project may/may not be the exact match you’re looking for. Which is why we have specified use cases and categorized the tools in this Python libraries list for data visualization so you know which one is best suited for your project.

5. Bokeh (GitHub: Fork – 4.1K | Star – 17.9K)

Bokeh is an interactive tool for data visualization in Python that provides modern charting capabilities for web browsers. It is most preferable when you need to develop dashboards or interactive plots for complicated data assets. It is based on The Grammar of Graphics like GGPlot, however it is based on Python whereas GGPlot supports multiple programming languages and is mainly used with R.

Bokeh comes with three different levels for creating visualizations. Level one focuses on creating quick data plots, level two controls the building blocks of the plot and level three is for experienced developers that can create and customize charts as per their needs with no pre-defined defaults. You might be able to handle level 1 and level 2 type of charting requirements yourself, but we recommend you to hire Python developers with proven experience and expertise to integrate level 3 into your project.

You can install Bokeh from the official PyPi repository by clicking here.

Bokeh is the best interactive Python data visualization tool when you need to: 

• Fulfil common plotting requirements
• Create highly interactive and scalable visualizations like graphs
• Create highly custom-made visualizations

6. PyGal (GitHub: Fork – 417 | Star – 2.6K)

PyGal is a beautiful Python charting library that is primarily used for building SVG graphs and chart visualizations for Python data. PyGal allows developers to create proper graphs with minimal lines of code.

You can embed charts made with PyGal into web pages just like with Bokeh or Plotly. However, a stark difference that makes PyGal standout is that it can output the charts in SVG format which means you will be able to analyse your Python chart clearly without any quality reduction when you upscale or downscale them. One limitation of this SVG base approach can be that it can get overly complicated with complex data. So, using PyGal for small to medium Python visualization needs is ideal.
