no point type?

Similary like in rviz markers, isn't their any type in rviz_visual_tools which can be used for that points and point lists? 
I tried to uyse cube instead of points but after this i can't do anything in rviz i.e it freezes. 
But when i use the points of visualization_msgs/marker type and publsih from publishMarker it is not showing the color.
