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

Before using pygwalker, make sure to install the packages through the command line using pip.
pip install pygwalkerNote
For an early trial, you can install with
pip install pygwalker --upgradeto keep your version up to date with the latest release or evenpip install git+https://github.com/Kanaries/pygwalker@mainto obtain latest features and bug-fixes.
Import pygwalker and pandas to your Jupyter Notebook to get started.
import pandas as pd
import pygwalker as pygYou 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)You can even try it online, simply visiting
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.
-
You can save the data exploration result to a local file
