# Manpages - graphviz.7

## Table of Contents

## NAME

graphviz - rich set of graph drawing tools

## SYNOPSIS

This manpage has been written to fulfil the need of a centralized documentation presenting all available tools in the graphviz package.

## AVAILABLE TOOLS

### Graph layout programs

**dot**- filter for hierarchical layouts of graphs
**neato**- filter for symmetric layouts of graphs
**twopi**- filter for radial layouts of graphs
**circo**- filter for circular layout of graphs
**fdp**- filter for symmetric layouts of graphs

All of the filters work with either directed or undirected graphs,
though **dot** is typically used for directed graphs and **neato** for
undirected graphs. Note also that **neato -n[2]** can be used to render
layouts produced by the other filters.

### Graph drawing programs

**lefty**- A Programmable Graphics Editor
**lneato**- lefty + neato
**dotty**- lefty + dot

### Graph layout enhancement

**gvcolor**- flow colors through a ranked digraph
**unflatten**- adjust directed graphs to improve layout aspect ratio
**gvpack**- merge and pack disjoint graphs

### Graph information and transformation

**gc**- count graph components
**acyclic**- make directed graph acyclic
**nop**- pretty-print graph file
**ccomps**- connected components filter for graphs
**sccmap**- extract strongly connected components of directed graphs
**tred**- transitive reduction filter for directed graphs
**dijkstra**- single-source distance filter
**bcomps**- biconnected components filter for graphs
**gvpr**- graph pattern scanning and processing language
**prune**- prune directed graphs

### Other

**gxl2dot, dot2gxl**- GXL-DOT converters

This manual page was written by Cyril Brulebois <cyril.brulebois@enst-bretagne.fr> in november 2006, based on an initial documentation effort by Joachim Berdal Haga <jbh@lupus.ig3.net>. It can be distributed under the same terms as the graphviz package.
