Dear RosNodeViewer: What a cool ROS node viewer !!

[takeshi-iwanari]

Hi,

I'd like to share a ROS node viewer named Dear RosNodeViewer. It will be useful to see a node structure of complicated system like Autoware.
It can analyze and visualize a running ROS graph like rqt_graph but the generated diagram is well-organized and easy to see. In addition, it can load a pre-created graph file. The following two formats are currently supported:

• dot file
• architecture file generated by CARET

Dear RosNodeViewer is available on PyPI. You can try it using the following few lines. This demo shows a node diagram of Autoware (Rosbag replay simulation) using CARET architecture file I prepared.

# Install requirements
sudo apt install graphviz graphviz-dev

# Install Dear RosNodeViewer
pip install dear-ros-node-viewer

# Download sample graph
wget https://raw.githubusercontent.com/takeshi-iwanari/dear_ros_node_viewer/main/sample/architecture_autoware.yaml

# Run Dear RosNodeViewer
dear_ros_node_viewer architecture_autoware.yaml
