python-plplot-qt

Scientific plotting library (Python 2 Qt GUI)

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.

xul-ext-nosquint

control the size of text of websites

NoSquint allows you to adjust the text-only and full-page (both text and images) zoom levels as well as color settings both globally (for all sites) and per site. Having a hard time reading on the web? Is that website with the ridiculously small font and hot-pink-on-slightly-darker-hot-pink text raising your blood pressure? NoSquint can:

libtext-unidecode-perl

US-ASCII transliterations of Unicode text

It often happens that you have non-Roman text data in Unicode, but you can't display it -- usually because you're trying to show it to a user via an application that doesn't support Unicode, or because the fonts you need aren't accessible. You could represent the Unicode characters as "???????" or "\15BA\15A0\1610...", but that's nearly useless to the user who actually wants to read what the text says.

libpostscript-simple-perl

Perl library for generating postscript files

PostScript::Simple allows you to have a simple method of writing PostScript files from Perl. It has several graphics primitives that allow lines, circles, polygons and boxes to be drawn. Text can be added to the page using standard PostScript fonts.
