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 lay-
out 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.
