If nothing else, remember that subgraphs must start with "cluster", yes in their identifier name, to be visually distinguishable i.e. apply label/color augh.

SVG

  • graphviz tools generate svg via -Tsvg
  • notugly is some XSL to beautify dot's SVG output

Examples

Generated using Graphviz 2.20.2 and postprocessing via xsltproc and notugly. I hand-wrote the dot sources.
