Topic Graph

Display a graph visualization of the current node and topic topology.

Connect to a live ROS system using the native connector for best results.

The graph will show nodes, topics, and services. Nodes implement services, and either subscribe to or publish topics. The direction of the graph's arrows will denote whether a node is subscribing to or publishing a topic.

  • Nodes – blue rectangles
  • Topics – purple diamonds
  • Services – red rectangles

If any items in the graph are overlapping, click and drag to reposition them for easier viewing.
