Rviz is a good visualization, but it focuses on a

3d environment. Rviz, in my experience, represents the interactions of the
robot (with its sensors) in the environment, you can draw maps and do a lot
of things.
rviz is not only for 3D but also for 2D viz. Look at this video for example:
http://wiki.ros.org/navigation/Tutorials/Using%20rviz%20with%20the%20Naviga…
However, rviz does not provide access to the data
itself. Long history
short, while I can see there is an object with the laser scan at a certain
distance, I can not see the actual distance of the object. Sometimes we want
more info about the data to see what values are best suited to use in our
programs.
Yes, you are right rviz does not provide access to the data and is
quite difficult to customize to specific needs.
You have to write plugins in order to add more visualisations.
Having a robotic data viz engine that could be extended with ROASSAL
scripting could be nice.
This is what you are trying to do ?
