3
unflatten \- adjust directed graphs to improve layout aspect ratio
19
used to improve the aspect ratio of graphs having many leaves
20
or disconnected nodes.
21
The usual layout for such a graph is generally very wide or tall.
23
inserts invisible edges or adjusts the \fBminlen\fP on edges
24
to improve layout compaction.
26
The following options are supported:
29
The minimum length of leaf edges is staggered
30
between 1 and \fIlen\fP (a small integer).
33
Enables adjustment of fanin-fanout chains (example: a -> {w x y z} -> b),
34
i.e., nodes with indegree and outdegree equal to 1 are also staggered.
37
Form disconnected nodes into chains of up to \fIlen\fP nodes.
40
causes the output to be written to the specified file; by default,
41
output is written to \fBstdout\fP.
43
The following operand is supported:
46
Names of files containing 1 or more graphs in dot format.
50
the standard input will be used.
