(e.g., technical illustrations and drawings) from a geometric/algebraic description, with standard features including the drawing of points, lines, arrows, paths, circles, ellipses and polygons. PGF is a lower-level language, while Ti''k''Z is a set of higher-level macros that use PGF. The top-level PGF and Ti''k''Z commands are invoked as TeX macros, but in contrast with PSTricks, the PGF/Ti''k''Z graphics themselves are described in a language that resembles

PGF/Ti''k''Z comes with an extensive documentation; the version 3.1.4a of the manual has over 1300 pages. The standard LaTeX picture environment can also be used as a front end for PGF — by merely using the pgfpict2e package. The project has been under constant development since 2005. Most of the development is done by Till Tantau. Version 3.0.0 was released on 20 December 2013. One of the major new features of this version was
