PLplot is relatively small, portable, freely distributable, and is rich enough to satisfy most users. It has a wide range of plot types including line (linear, log), contour, 3D, fill, and almost 1000 characters (including Greek and mathematical) in its extended font set. The package is designed to make it easy to quickly get graphical output; only a handful of function calls is typically required. For more advanced use, virtually all aspects of plotting are configurable.

This package converts the buffer text and the associated decorations to HTML. It supports three types of HTML output, selected by setting htmlize-output-type: css, inline-css (optimized for code snippets), and font (simpler output, doesn't rely on CSS). You can also use htmlize from your Emacs Lisp code.

This tool provides conversions between Glyphs source files (.glyphs) and Unified Font Objects (UFOs) via defcon.
