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.
