Vision-impaired students have several issues accessing mathematical documents, which are associated with the
representation of mathematical expressions and graphs of mathematical functions. Graphs of mathematical
functions are visual presentations of mathematical information and useful to illustrate numerical or qualitative
information, which are sometimes difficult or even impossible to describe. A graph is a picture that shows how
sets of data are related to each other. Graphs of mathematical functions generally convey the intended message
of a mathematical document. Therefore, access to graphs is essential in learning mathematics. Finding a solution
to represent graphs of mathematical functions in an accessible format is necessary for the vision-impaired. This
paper describes an approach to develop an application to address this issue by detecting, extracting and
categorising important information from graphs of mathematical functions using three open source packages,
namely, ImageMagick, GNUPLOT and Octave.
