Visual rendering by Graphviz. This graph visualises the relationship between a group of bloggers.

Undirected graph showing adjacency of the 48 contiguous United States

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.

Architecture

Graphviz consists of a graph description language named the DOT language^[2] 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")

twopi 

for radial graph layouts.

circo 

for circular graph layouts.

fdp 

another layout engine for undirected graphs.

dotty 

a graphical user interface to visualize and edit graphs.

lefty 

a programmable (in a language inspired by EZ^[3]) 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
