edgepaint

Colorize edges of a graph layout to clarify crossing edges. Graphviz filters: acyclic, bcomps, comps, edgepaint, gvcolor, gvpack, mingle, nop, sccmap, tred, & unflatten. More information: https://graphviz.org/pdf/edgepaint.1.pdf.

• 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
