graphviz - rich set of graph drawing tools


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


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.
