ASYMPTOTE Copyright 2004-2026 Andy Hammerlindl, John Bowman, and Tom Prince

Asymptote is a powerful descriptive vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. Asymptote provides for figures the same high-quality level of typesetting that LaTeX does for scientific text.

Installation instructions, documentation, binaries, and source code are available at:
