Node graph

Nodes and topics as a graph, like rqt_graph.

• Filter by name, and hide debug topics or topics nobody listens to (dead ends).

• Pinch to zoom, drag to move and double-tap to fit everything on screen.

• Tap a node to highlight its connections; tap it again to open its parameters.

Participants that don’t announce ROS node names (other DDS programs) appear with their DDS name. The graph is also available from Home, without creating a tab.
