# graphviz(7)

rich set of graph drawing tools

## 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.

### 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.
