Hello, I'm trying to explore rviz for line visualization. I am trying to follow the tutorial from http://docs.ros.org/hydro/api/rviz_py... , but when I try to execute the file, I get an error

AttributeError: 'module' object has no attribute 'VisualizationFrame'

I'm not sure why I'm getting this error. I'm using ros-indigo.

Please help.

I an new to ROS and am trying to understand the units in which the values in the Odometry.orientation.w and z fields and what do they represent. I am trying to rotate a turtlebot by a specific number of degrees. Is there a way to achieve it as I am able to set only angular velocities and whose unit I don't know either.
