# ipydagred3 — ipywidgets wrapper around dagre-d3

License: permissive · Maintenance: active · Downloads: 424.0K/mo

## What it is and what it does

ipydagred3 wraps the dagre-d3 graph layout engine as an interactive ipywidgets component for Jupyter notebooks and JupyterLab. It lets you create, modify, and visualize directed acyclic graphs directly from Python code, with support for customizing node colors, shapes, and tooltips. The widget emits click events when users interact with nodes or edges, making it suitable for building interactive graph inspection tools and exploratory workflows within notebooks.

The package is designed for developers working in Jupyter environments who need to visualize DAG structures—such as workflow dependencies, computational graphs, or data lineage—without leaving the notebook. It requires only ipykernel and ipywidgets, both standard Jupyter dependencies, and supports Python 3.8 through 3.12.

Use it for:

- Visualizing workflow or task dependency graphs in a notebook for debugging or documentation
- Building interactive node inspectors that respond to clicks on graph elements
- Exploring data lineage or computational DAGs with dynamic node and edge styling
- Prototyping graph-based applications where users need to see and interact with DAG structure

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

ipydagred3 is an ipywidgets library for rendering and interacting with directed acyclic graphs in JupyterLab, built on dagre-d3 for layout and visualization.

Yes, if you work in JupyterLab and need to visualize or interact with DAGs. The package is actively maintained, has no known vulnerabilities, installs with minimal friction, and carries a permissive Apache License Version 2.0. The last release was 2023-10-31 but recent commit activity on 2026-08-01 indicates ongoing maintenance; verify compatibility with your JupyterLab version before production use.

## Install

pip install ipydagred3
uv add ipydagred3
poetry add ipydagred3

## Installing ipydagred3

Before you install: Installation is straightforward via pip with low friction. The package is actively maintained as of 2026-08-01, with recent commit history and no archived status. It depends only on ipykernel and ipywidgets, both stable Jupyter ecosystem libraries.

License in practice: Licensed under Apache License Version 2.0 (permissive), which allows free use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects as long as license and copyright notices are retained.

Quickstart:

pip install ipydagred3

from ipydagred3 import Graph

graph = Graph()
graph.add_node('node1', label='Task 1')
graph.add_node('node2', label='Task 2')
graph.add_edge('node1', 'node2')
graph

Verify before relying:

- Whether the package works with the latest JupyterLab versions beyond what the classifiers indicate
- Performance characteristics when rendering large or complex DAGs
- Stability of click event handling and tooltip features in production use
