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 adjustment of fanin-fanout chains (example: a -> {w x y z} -> b),
i.e., nodes with indegree and outdegree equal to 1 are also staggered.
-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.
