The package provides the means to use PDF drawing primitives to produce high quality, colored graphics. It

• uses Bézier curves (integral and rational) from degree one to seven,
• allows TeX typesetting in the graphic,
• offers most of the standard math functions,
• allows plotting normal, parametric and polar functions.

The package has linear, logx, logy, logxy and polar grids with many specs;

• it can rotate, clip and do many nice things easily
• it has two looping commands for programming and many instructive example files.

The package requires pdfTeX but otherwise only depends on the calc package.
