rqt Graph is a tool that visually shows the communication structure between the nodes and topics running in a ROS system. It lets you see intuitively how robot software is exchanging data. Its main features are as follows: - Visualizing connections between nodes: see as a network which nodes publish or subscribe to which topics. - Topic monitoring: watch the flow of messages exchanged on each topic in real time. - Debugging complex systems: helps troubleshooting by showing at a glance the communication structure of a complex system made up of many nodes.
