title: How can I visualize rviz publish points?
body: <p>I want to combine the publish points via ros-rviz by ticking, but I don't know how to do this exactly, which resources should I look at, is there a sample study?</p>
  <p>What I want is done on frontier exploration ros wiki, but how can I add it on a different rviz? How can I make this visualization by giving it publish point?</p>
