PyGWalker: A Python Library for Exploratory Data Analysis with Visualization

PyGWalker can simplify your Jupyter Notebook data analysis and data visualization workflow. By turning your pandas dataframe into a Tableau-style User Interface for visual exploration.

PyGWalker (pronounced like "Pig Walker", just for fun) is named as an abbreviation of "Python binding of Graphic Walker". It intergrates Jupyter Notebook (or other jupyter-based notebooks) with Graphic Walker, a different type of open-source alternative to Tableau. It allows data scientists to analyze data and visualize patterns with simple drag-and-drop operations.

Visit Google Colab, Kaggle Code, or Graphic Walker Online Demo to test it out!

PyGWalker will add more support such as R in the future.

Getting Started

Tested Environments

• Jupyter Notebook
• Google Colab
• Kaggle Code
• Jupyter Lab (WIP: There're still some tiny CSS issues)
• Visual Studio Code
• ...feel free to raise an issue for more environments.

Run in Kaggle	Run in Colab

Setup pygwalker

Before using pygwalker, make sure to install the packages through the command line using pip.

pip install pygwalker

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 changing 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)

You can even try it online, simply visiting , Google Colab or Kaggle Code.

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 save the data exploration result to a local file.
