Using Neo4j, Kuzu, or SPARQL? Use our dedicated integrations instead: Neo4j · Kuzu · SPARQL

A graph visualization widget for Jupyter Notebook and JupyterLab powered by yFiles for HTML.

Visualize graphs from many sources out of the box:

• NetworkX ✅
• igraph ✅
• neo4j ✅ (use the dedicated neo4j package)
• pygraphviz ✅
• Native Python dicts/lists ✅

Many more formats are supported via NetworkX imports.

Key Features

• Fast, production-grade graph rendering (yFiles engine)
• Multiple automatic layouts (hierarchical, organic, circular, ...)
• Data-driven styling (colors, sizes, labels, ...) from node/edge attributes
• Sidebars for search, data inspection, and neighborhood exploration
• Heatmaps and map visualization

Choose your path

There are extensions built on top of yfiles-jupyter-graphs that provide tailored APIs and convenient data mapping for their respective ecosystems:

• If you work with Neo4j: use yfiles-jupyter-graphs-for-neo4j
• If you work with Kuzu: use yfiles-jupyter-graphs-for-kuzu
• If you query via SPARQL: use yfiles-jupyter-graphs-for-sparql

Otherwise, continue below with yfiles-jupyter-graphs.

Where it runs

• JupyterLab or Jupyter Notebook
• Visual Studio Code
• Google Colab
• Gemini Enterprise Agent Platform
• Managed Service for Apache Spark
• Azure Machine Learning Studio Notebooks
• Amazon SageMaker
• Kaggle
• Just try it in your preferred platform for Jupyter notebooks

AI Coding Assistant

Working with an AI coding agent? Our agent guide contains instructions and best practices for coding agents.

Example start prompt:

Read the instructions at https://raw.githubusercontent.com/yWorks/yfiles-jupyter-graphs/refs/heads/main/agent-guide.md. Then, create a new Jupyter notebook that step-by-step explores the and visualizes it using yfiles-jupyter-graphs. Be creative and design visualizations that highlight interesting insights and aspects of the data.

Install

Prerequisites:

• python >= 3.7
• jupyter notebook or lab
• ipywidgets >= 7.6.0

pip install yfiles-jupyter-graphs

Important: When installing from inside a notebook, prefer %pip install yfiles-jupyter-graphs over !pip install to ensure the package is installed into the running kernel’s environment.

Docker (optional)

If you want to start with a clean Jupyter environment that has the widget preinstalled:

mkdir yfiles-jupyter && cd yfiles-jupyter
echo -e "FROM jupyter/scipy-notebook\nRUN pip install yfiles-jupyter-graphs" > Dockerfile
docker build -t yfiles-jupyter-graphs-on-docker .
docker run -it -p 8888:8888 --name yfiles-jupyter yfiles-jupyter-graphs-on-docker

This approach has been verified with scipy-notebook:lab-3.4.7 and yfiles-jupyter-graphs==1.2.1. If you encounter issues with a newer image, please open an issue.

Quickstart

Display a simple graph:

from yfiles_jupyter_graphs import GraphWidget, Node, Edge
w = GraphWidget(
    nodes=[
        Node(id=0, properties={"firstName": "Alpha", "label": "Person A"}),
        Node(id=1, properties={"firstName": "Bravo", "label": "Person B"}),
        Node(id=2, properties={"firstName": "Charlie", "label": "Person C", "has_hat": False}),
        Node(id=3, properties={"firstName": "Delta", "label": "Person D", "likes_pizza": True})
    ],
    edges=[
        Edge(start=0, end=1, properties={"since": "1992", "label": "knows"}),
        Edge(start=1, end=3, properties={"label": "knows", "since": "1992"}),
        Edge(start=2, end=3, properties={"label": "knows", "since": "1992"}),
        Edge(start=0, end=2, properties={"label": "knows", "since": 234})
    ],
    directed=True
)
display(w)

Use the toolbar and sidebar to inspect data, search graph, explore neighborhood and change layouts.
