To clarify, I'm not suggesting that most blind users would want to examine
files of coordinates, though some might.  My interest is in having the data
available so that another program could represent the data sonically.

One typical way this sort of thing is done is to perform a scan along the X
axis, mapping the Y axis onto frequency.  So, the user hears a tone whose
pitch goes up and down during the scan.  I'm not at all sure how other data
(e.g., tangent line) should be represented, but having this sort of data
available in a structured form might allow someone to play around.
