Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs specified in DOT language scripts. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

Software architecture

Graphviz consists of a graph description language named the DOT language and a set of tools that can generate and/or process DOT files:

dot 

a command-line tool to produce layered drawings of directed graphs in a variety of output formats (PostScript, PDF, SVG, annotated text and so on).

neato 

for "spring model" layout (in Mac OS version called "energy minimised")

sfdp 

a layout engine for undirected graphs that scales to very large graphs.

fdp 

another layout engine for undirected graphs.

twopi 

for radial graph layouts.

circo 

for circular graph layouts.

dotty 

a graphical user interface to visualize and edit graphs.

lefty 

a programmable (in a language inspired by EZ) widget that displays DOT graphs and allows the user to perform actions on them with the mouse. Lefty can therefore be used as the view in a model-view-controller GUI application that uses graphs.

Applications that use Graphviz

• ArgoUML's alternative UML Diagram rendering called argouml-graphviz.
• AsciiDoc can embed Graphviz syntax as a diagram.
• ConnectedText has a Graphviz plugin.
• Doxygen uses Graphviz to generate diagrams including class hierarchies and collaboration for source code.
• Bison is able to output the grammar as dot for visualization of the language.
• Gephi has a Graphviz plugin.
• Gramps uses Graphviz to create family trees.
• Omnigraffle Version 5 and above uses the Graphviz engine (with a limited set of commands) for automatically laying out graphs.
• Org-mode can work with DOT source code blocks
• PlantUML uses Graphviz to generate UML diagrams from text descriptions.
