The MetaPost output from my Function Grapher
http://www.tlhiv.org/mpgraph/
is now available in ConTeXt format. This can be illustrated by choosing a graph type and selecting an example from one of the Example buttons. Once the graph is drawn, the ConTeXt source can be downloaded using the "Download" drop-down box. Simply executing `context mpgraph.tex` should produce the same graph viewed on the website in PDF. If you see any bugs, feel free to let me know.
