Yes, paper is by far the easiest, but if you're good with moving the
Braille display about and forming a picture in you're mind based on what
you have seen and what is shown on the display, the maxima dumb plot is
useful. 
Essentially it's just a text based drawing using ascii character to show
the shapes on the diagram. Very good for graphs etc. I used this as my
CAS solution in high school math. It worked well to get an overview of
say the graph I need to sketch in the calc access exam or even in
classes to picture what the teacher had drawn on the board. 

Got a bit messy when you have more than 2 graphs though.
