ZeGrapher v4 is a free, open-source math plotter with a modern interface, inspired by Desmos. The project was first released in 2011, and its author has maintained it sporadically since then. Version 4 is a near-complete rewrite that reflects a substantial amount of work.
Notable features include computing and plotting recursive sequences, and exporting SVG and PDF files at the physical size shown on screen or set in centimeters.
