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.
-? 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.
