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.
