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.
