PGF/TikZ

The PGF/TikZ interpreter can be used from the popular LaTeX and ConTeXt macro packages, and also directly from the original TeX. Since TeX itself is not concerned with graphics, the interpreter supports multiple TeX output backends: dvips, dvipdfm/dvipdfmx/xdvipdfmx, TeX4ht, and pdftex's internal PDF output driver. PGF/TikZ comes with an extensive documentation; the version 3.1.4a of the manual has over 1300 pages. Most of the development until 2018 was done by Till Tantau and since then Henri Menke has been the main contributor. Version 3.0.0 was released on 20 December 2013. One of the major new features of this version was graph drawing using the graphdrawing package, which however requires LuaTeX. This version also added a new data visualization method and support for direct SVG output via the new dvisvgm driver. ==Export==

Several graphical editors can produce output for PGF/TikZ, such as the KDE program Cirkuit and the math drawing program GeoGebra. Export to TikZ is also available as extensions for Inkscape, Blender, MATLAB, matplotlib, Gnuplot, Julia, and R. The circuit-macros package of m4 macros exports circuit diagrams to TikZ using the dpic -g command line option. The dot2tex program can convert files in the DOT graph description language to PGF/TikZ. ==Libraries==

TikZ features libraries for easy drawing of many kinds of diagrams, such as the following (alphabetized by library name): • 3D drawing3d • Finite automata and Turing machinesautomata • Coordinate system calculationscalc • Calendarscalendar • Chains: nodes typically connected by edges and arranged in rows and columnschain • Logic circuit and electrical circuit diagramscircuits.logic and circuits.ee • Entity–relationship diagramser • Polygon folding diagramsfolding • Graph drawing with automatic layout optionsgraphdrawing • L-system drawingslindenmayersystems • Sequences of basic math operationsmath • Matricesmatrix • Mind mapsmindmap • Three-point perspective drawingsperspective • Petri netspetri • Quantum circuitsquantikz • RDF semantic annotations (only in SVG output)rdf • Special shapes and symbolsshapes.geometric and shapes.symbols • Magnification of part of a graphic in an insetspy • Paths in SVG syntaxsvg.path • Treestrees • Turtle graphicsturtle • Zooming and panning graphicsviews ==Gallery==

The following images were created with TikZ and show some examples of the range of graphic types that can be produced. The link in each caption points to the source code for the image.
