UNFLATTEN(1)						      General Commands Manual						      UNFLATTEN(1)

NAME

       unflatten - adjust directed graphs to improve layout aspect ratio

SYNOPSIS

       unflatten [-f] [-llen] [-clen ] [ -o outfile ] [ files ]

DESCRIPTION

       unflatten  is a preprocessor to dot that is used to improve the aspect ratio of graphs having many leaves or disconnected nodes.  The usual
       layout for such a graph is generally very wide or tall.	unflatten inserts invisible edges or adjusts the minlen on edges to improve layout
       compaction.

OPTIONS

       The following options are supported:

       -l len The minimum length of leaf edges is staggered between 1 and len (a small integer).

       -f     Enables  the staggering of the -l option to fanout nodes whose indegree and outdegree are both 1. This helps with structures such as
	      a -> {w x y z} -> b.  This option only works if the -l flag is set.

       -c len Form disconnected nodes into chains of up to len nodes.

       -o outfile
	      causes the output to be written to the specified file; by default, output is written to stdout.

OPERANDS

       The following operand is supported:

       files   Names of files containing 1 or more graphs in dot format.  If no files operand is specified, the standard input will be used.

NAME

       tred - transitive reduction filter for directed graphs

SYNOPSIS

       tred [ files ]

DESCRIPTION

       tred  computes the transitive reduction of directed graphs, and prints the resulting graphs to standard output.  This removes edges implied
       by transitivity.  Nodes and subgraphs are not otherwise affected.  The ``meaning'' and validity of the reduced graphs is application depen-
       dent.  tred is particularly useful as a preprocessor to dot to reduce clutter in dense layouts.

       Undirected graphs are silently ignored.

OPERANDS

       The following operand is supported:

       files   Names of files containing 1 or more graphs in dot format.  If no files operand is specified, the standard input will be used.

BUGS

       Using bitmaps internally would substantially decrease running time.

DIAGNOSTICS

       If a graph has cycles, its transitive reduction is not uniquely defined.  In this case tred emits a warning.
