As a programmer, you are always on the lookout for ways to make your job easier. Data visualization is a critical component of data analysis, but creating effective visualizations can be time-consuming and require extensive coding. Fortunately, there are open-source Python libraries that can help you create data visualizations with minimal coding. In this article, we will explore some of the best open-source Python libraries for minimal coding data visualizations.
PyGWalker is an open-source Python library that allows data scientists to turn their pandas DataFrame into a Tableau-style user interface for visual analysis. With PyGWalker, you can create stunning visualizations with simple drag-and-drop operations. It works with both pandas and polars, making it a versatile tool for data visualization.

Before using pygwalker, make sure to install the packages through the command line using pip or conda.
pip install pygwalker
For an early trial, you can install with
pip install pygwalker --upgradeto keep your version up to date with the latest release or even
pip install git+https://github.com/Kanaries/pygwalker@mainto obtain latest features and bug-fixes.
conda install -c conda-forge pygwalker
mamba install -c conda-forge pygwalker
See conda-forge feedstock for more help.
Run PyGWalker online
You can run PyGWalker in Google Colab, Kaggle Code, Binder or Graphic Walker Online Demo to test it out!
Use pygwalker in Jupyter Notebook
Import pygwalker and pandas to your Jupyter Notebook to get started.
import pandas as pd import pygwalker as pyg
You can use pygwalker without breaking your existing workflow. For example, you can call up Graphic Walker with the dataframe loaded in this way:
df = pd.read_csv('./bike_sharing_dc.csv', parse_dates=['date']) gwalker = pyg.walk(df)
And you can use pygwalker with polars (since
import polars as pl df = pl.read_csv('./bike_sharing_dc.csv',try_parse_dates = True) gwalker = pyg.walk(df)
That's it. Now you have a Tableau-like user interface to analyze and visualize data by dragging and dropping variables.
Cool things you can do with Graphic Walker:
You can change the mark type into others to make different charts, for example, a line chart:
To compare different measures, you can create a concat view by adding more than one measure into rows/columns.
To make a facet view of several subviews divided by the value in dimension, put dimensions into rows or columns to make a facets view. The rules are similar to Tableau.
You can view the data frame in a table and configure the analytic types and semantic types.
Matplotlib is a popular Python library for creating static, animated, and interactive visualizations in Python. It provides an easy-to-use interface for creating complex visualizations with just a few lines of code. With Matplotlib, you can create line plots, scatter plots, bar plots, histograms, and much more.
