unflatten — Adjust directed graphs to improve the layout aspect ratio. Graphviz filters: acyclic, bcomps, comps, edgepaint, gvcolor, gvpack, mingle, nop, sccmap, tred, and unflatten. More information: <https://www.graphviz.org/pdf/unflatten.1.pdf>.

Adjust one or more directed graphs to improve the layout aspect ratio:

unflatten {{path/to/input1.gv path/to/input2.gv ...}} > {{path/to/output.gv}}

Use unflatten as a preprocessor for dot layout to improve aspect ratio:

unflatten {{path/to/input.gv}} | dot -T {{png}} {{path/to/output.png}}
