# Dear RosNodeViewer
## About
- Visualize ROS2 node diagram
- Support the following sources:
- *architecture.yaml* generated by [CARET](https://github.com/tier4/caret)
- *rosgraph.dot* generated by rqt_graph
- running ROS graph analysis
## Requirements
- Ubuntu 20.04 or 22.04
- graphviz is required
- optional: ROS 2 Galactic or Humble if you need runtime ROS graph analysis
- Not tested in Windows / Mac
## Get Started
```sh
# Install requirements
sudo apt install graphviz
# Install Dear RosNodeViewer
pip install dear-ros-node-viewer
# Download sample graph
wget https://raw.githubusercontent.com/iwatake2222/dear_ros_node_viewer/main/sample/architecture_autoware.yaml
# Run Dear RosNodeViewer
dear_ros_node_viewer architecture_autoware.yaml
```
- Quick operation guide:
- Middle button drag: move graph area
- Mouse scroll: zoom in/out (zoom function is tentative)
