visualization_msgs
This package provides messages for visualizing 3D information in ROS GUI programs, particularly RViz.
These messages were ported from ROS 1 and for now the visualization_msgs wiki is still a good place for information about these messages and how they are used.
For more information about ROS 2 interfaces, see docs.ros.org.
