graphviz

; dot : a command-line tool to produce layered graph drawings in a variety of output formats, such as (PostScript, PDF, SVG, annotated text and so on).

; neato : useful for undirected graphs up to about 1000 nodes. "Spring model" layout minimizes global energy.

; fdp : force-directed graph drawing similar to "spring model", but minimizes forces instead of energy. Useful for undirected graphs.

; sfdp : multiscale version of fdp for the layout of large undirected graphs.

; twopi : for radial graph layouts. Nodes are placed on concentric circles depending on their distance from a given root node.

; circo : circular layout. Suitable for certain diagrams of multiple cyclic structures, such as certain telecommunications networks.

; dotty : a graphical user interface to visualize and edit graphs.

; lefty : a programmable (in a language inspired by [http://portal.acm.org/citation.cfm?id=318642 EZ][http://graphviz.org/pdf/leftyguide.pdf The Lefty guide (“Editing Pictures with lefty”)], section 3.1, p. 9.) widget that displays DOT graphs and allows the user to perform actions on them with the mouse. Therefore, Lefty can be used as the view in a model–view–controller GUI application that uses graphs.

; gml2gv, gv2gml: convert to/from GML, another graph file format.

; graphml2gv: convert a GraphML file to the DOT format.

; gxl2gv, gv2gxl: convert to/from GXL, another graph file format.
