Data visualization is the visual presentation of data or information. The goal of data visualization is to communicate data or information clearly and effectively to readers. Typically, data is visualized in the form of a chart, infographic, diagram, map and more.
How does it help?
- Identify trends and outliers
- Tell a story within the data
- Reinforce an argument or opinion
- Highlight an important point in a set of data
Let's dive into each of them.
Use the package manager
pip to install below:
pip install matplotlib pip install seaborn pip install plotnine pip install plotly pip install bokeh
Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. Most of the coders start their Data Visualisation journey with Matplotlib.
- It is designed like MATLAB hence switching between the two is fairly easy.
- Comprises a lot of rendering backends.
- It can reproduce just about any plots (with a bit of effort).
- Has been out there for over a decade, therefore, boasts of a huge user base.
Seaborn harnesses the power of Matplotlib to create beautiful charts in a few lines of code. The key difference is Seaborn’s default styles and color palettes, which are designed to be more aesthetically pleasing and modern. Since Seaborn is built on top of Matplotlib, you'll need to know Matplotlib to tweak Seaborn's defaults.
- Built in themes for styling matplotlib graphics
- Visualizing univariate and bivariate data
- Fitting in and visualizing linear regression models
- Plotting statistical time series data
- Seaborn works well with NumPy and Pandas data structures
- It comes with built in themes for styling Matplotlib graphics
Plotnine is an implementation of a grammar of graphics in Python, it is based on ggplot2. The grammar allows users to compose plots by explicitly mapping data to the visual objects that make up the plot.
- Statistical transformations
- Coordinates systems

Bokeh is an interactive visualization library for modern web browsers. It provides elegant, concise construction of versatile graphics, and affords high-performance interactivity over large or streaming datasets. Bokeh can help anyone who would like to quickly and easily make interactive plots, dashboards, and data applications.
plotly is an interactive, open-source, and browser-based graphing library for Python. Built on top of plotly.js, plotly.py is a high-level, declarative charting library. plotly.js ships with over 30 chart types, including scientific charts, 3D graphs, statistical charts, SVG maps, financial charts, and more.
- Charts, Dashboards
- File Export, App Manager
- Kubernetes, Authentication
- Jobs Queue, Snapshot Engine
- Embedding, Big Data for Python
