Graph Plotter

Grapher ><

This is an old graph plotting tool built sometime around year 2005, when online plotting tools were non-existent (to my knowledge). The output plot is generated purely in PHP from scratch, utilizing pixel-by-pixel basic line drawing capability without using any plotting package or 3rd party utility.

This tool can plot graph from a list of data points or from a mathematical function. See a demo here.
