Editing Graphviz (section)

== Tools ==

; dot : a [[Command-line interface|command-line]] tool to produce [[layered graph drawing|layered graph drawings]] in a variety of output formats, such as ([[PostScript]], [[PDF]], [[Scalable Vector Graphics|SVG]], annotated text and so on).
; neato : useful for [[undirected graph]]s up to about 1000 nodes. "[[Spring system|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]<ref>[http://graphviz.org/pdf/leftyguide.pdf The Lefty guide (“Editing Pictures with lefty”)], section&nbsp;3.1, p.&nbsp;9.</ref>) [[Widget (GUI)|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 [[Graph_Modelling_Language|GML]], another graph file format.
; graphml2gv: convert a [[GraphML]] file to the DOT format.
; gxl2gv, gv2gxl: convert to/from [[GXL]], another graph file format.
