I’m not sure anyone has taken on the port of the rqt_rviz plugin. When we ported the RQT plugins to ROS2, this one was specifically avoided due to the large amount of work involved and the timeline we were working under. Alberto from iRobot also looked into it, but I’m not sure if they were able to make any progress on it. It’s likely a large undertaking and would require some dedicated effort from knowledgeable individuals.
