UNFLATTEN(1) UNFLATTEN(1) 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. AUTHORS Stephen C.

NAMEunflatten − adjust directed graphs to improve layout aspect ratio

SYNOPSISunflatten [−f] [−llen] [−clen ] [ −o outfile ] [ fi les ]

DESCRIPTIONunflatten is a preprocessor todot that is used to improve the aspect ratio of graphs having many leaves ordisconnected nodes.The usual layout for such a graph is generally very wide or tall.unflatten insertsinvisible edges or adjusts theminlen on edges to improve layout compaction.

OPTIONSThe following options are supported:

−l len The minimum length of leaf edges is staggered between 1 andlen (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 asa -> {w x y z} -> b. This option only works if the-l flag is set.

−c len Form disconnected nodes into chains of up tolennodes.

−o outfilecauses the output to be written to the specified file; by default, output is written tostdout.

OPERANDSThe following operand is supported:

files Names of files containing 1 or more graphs in dot format. If nofiles operand is specified, thestandard input will be used.
