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 very wide or tall. unflatten creates chains
with invisible edges or adjusts the minlen on edges to improve layout
compaction.
OPTIONS
The following options are supported:
-l len The minlen of leaf edges is staggered between 1 and len (a small
integer).
-f Applies 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 edges.
-o outfile
causes the output to be written to the specified file; by
default, output is written to stdout.
-? Prints the usage and exits.
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.
