http://www1.chapman.edu/~jipsen/mathml/asciimath.html is a great resource which has been around for a long time. The sandbox ( http://mathcs.chapman.edu/~jipsen/math/index.php/ASCIIMathML/ASCIIMathMLSandbox.html ) shows how to use graphs. It was initially designed to display math equations using MathML, but has been extended to calculate graphs, too.
