What would be the best way to display the output of a path planning algorithm such as a Rapidly-Exploring Random Tree? Instead of only displaying the best path, I would like to display several of the most highly rated paths.

I could create several nav_msgs/Path messages and then subscribe to them in rviz, but I feel like there might be a cleaner way to do this. What do you think the best way to do this would be?
