Get dot file of ROS graph w/o rqt_graph
I'm working on a headless rpi3 for ROS development with an IMU shield. Its not ideal but works for the purpose.
When building new nodes and connecting them would like to see the ros graph. I've looked at rqt_graph which is great but don't want to install all the X deps on the pi and really not prefer to forward X either.
I see that the now deprecated rxgraph does have a --dot=DOTFILE
argument, but rqt_graph does not. Is there any other way to export the graph as an image or dot file?
