Chinese: A Visit to Qiantang Lake in Spring (钱唐湖春行)
This example shows how to write simplified Chinese characters in LaTeX with the CJKutf8 package. WriteLaTeX includes a full set of fonts for simplified Chinese, and we use utf-8 encoding, so you can type simplified Chinese characters directly into your LaTeX source code and have them appear in the output.

Example: gnuplot + tikz
This is an example for re-creating gnuplot charts with tikz on LaTeX, made possible by adding gnuplot-lua-tikz.sty and gnuplot-lua-tikz-common.tex to your project. (These files can be generated by invoking lua gnuplot-tikz.lua style where gnuplot-tikz.lua can be found in $GNUPLOT/lua/gnuplot-tikz.lua.
(This will work with all engines, not just LuaLaTeX!)

Example of rotated text in LaTeX
A minimal example of rotated text in LaTeX. All you need is
