LaTeX can be used to produce a variety of different charts and diagrams, including: flowcharts, gantt charts, pie charts, branching and decision trees, family trees, histograms, bar charts and more. If you're looking for a particular type of chart that isn't featured here, please let us know, or submit your own example to the gallery.
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!)
Pakiet umożliwia robienie prostych grafów. Jest prosty i efektowny w działaniu. Kolejne polecenia \leaf umieszczają na stosie swoje parametry, a polecenia \branch zdejmują ze stosu wskazaną pierwszym argumentem liczbę obiektów i łączą je ukośnymi liniami; graf jest budowany w odwrotnej kolejności.
pgf-pie is a LaTeX package for drawing pie charts (and some interesting variants on pie charts) with the PGF/TikZ graphics package.
The examples in this document are from the pgf-pie manual, version 0.2.
