- Colorize edges of one or more graph layouts (that already have layout information) to clarify crossing edges:

`edgepaint {{path/to/layout1.gv}} {{path/to/layout2.gv ...}} > {{path/to/output.gv}}`

- Colorize edges using a color scheme. (See <https://graphviz.org/doc/info/colors.html#brewer>):

`edgepaint -color-scheme={{accent7}} {{path/to/layout.gv}} > {{path/to/output.gv}}`

- Lay out a graph and colorize its edges, then convert to a PNG image:

`dot {{path/to/input.gv}} | edgepaint | dot -T {{png}} > {{path/to/output.png}}`
