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.
