PGF is a macro package for creating graphics. It is platform- and
format-independent and works together with the most important TeX
backend drivers, including pdftex and dvips. It comes with a
user-friedly syntax layer called TikZ.
Its usage is similar to pstricks and the standard picture environment.
PGF works with plain (pdf-)TeX, (pdf-)LaTeX, and ConTeXt. Unlike
pstricks, it can produce either PostScript or PDF output.
