Graphviz (short for Graph Visualization Software) is a package of open source tools initiated by AT&T Research Labs 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 Common Public License.


[edit] Architecture

Graphviz consists of a graph description language named the DOT language[1] and a set of tools that can generate and/or process DOT files:

a command-line tool to lay out directed graphs into a variety of output formats (PostScript, PDF, SVG, annotated text and so on).
for "spring model" layout (in Mac OS version called "energy minimised")
for radial graph layouts.
for circular graph layouts.
another layout engine for undirected graphs.
a graphical user interface to visualize and edit graphs.
a programmable 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.
