AI Summary

This tool scans Python code from ROS2 projects to generate an interactive web-based graph visualizing nodes, topics, services, and their connections without requiring a running ROS2 environment.

How It Works

1
📖 Discover the tool

You hear about a handy visualizer that shows how parts of robot software connect just by looking at the code, no robot needed.

2
🛠️ Get it ready

Download the tool and set it up on your computer so it's ready to use.

3
📁 Choose your folder

Pick the folder with your robot project code that you want to explore.

4
🔍 Start the magic

Tell the tool to scan your code, and it quickly finds all the connections between software pieces.

5
🌐 View the graph

A colorful interactive map opens in your web browser, showing nodes as blue circles and topics as green shapes.

6
🖱️ Play and learn

Drag items around, hover for details, and zoom to see exactly how everything links up.

✅ Master your project

Now you fully understand your robot software's structure without ever turning on a real system—perfect for reviews or testing!

What is ros2grapher?

ros2grapher scans your ROS2 workspace's Python source code to generate an interactive graph of node topology, showing connections between nodes, topics, services, and message types like laser scan ros2 msg or lidar scan ros2. Point the CLI at a folder—ros2grapher /path/to/ws—and it serves a draggable, zoomable D3.js visualization in your browser at localhost:8888, no ROS2 install or running system required. Use --print for terminal output, --no-serve for static HTML, or --port for custom serving.

Why is it gaining traction?

Unlike rqt_graph or ros_network_viz, it works on cloned repos or in CI/CD pipelines without a live ROS2 setup, perfect for code reviews or scan github actions. It flags orphan topics, dynamic names, and groups by package, highlighting issues like unmatched ros2 scan topics or sick scan ros2 flows instantly. Developers grab it for quick topology checks on ros2 scan merger or ros2 scan matcher projects before launch.

Who should use this?

ROS2 package maintainers auditing connections in laser scan ros2 or ros2 scan filter nodes during pull requests. CI engineers adding it to scan github repo for vulnerabilities in topic graphs via GitHub Actions. Onboarding devs visualizing ros2 scan message flows without simulators, or teams scan github for malicious code in cloned ROS2 workspaces.

Verdict

Grab it for Python-only ROS2 projects if you need static topology views—installs easily with pip -e. At 12 stars and 1.0% credibility, it's early (v0.1.0, solid README, no tests yet), but MIT-licensed and CI-ready; watch for C++ support.
