Error: twoBigNodes0.gv: syntax error in line 246 near '}'
]
Here is a somewhat re-arranged version.
- swapped right & left sides of the 2 big nodes
- colored the edges (colorscheme | Graphviz & Color Names | Graphviz)
Arguably a bit better.
(I tried adding ranking to put node el4 between the two big nodes, but it was a disaster)
If there are ways to subset the edges, you might look at the layers capabilities (FAQ | Graphviz and Getting layers to work with SVG). This would allow you to show just a subset of the edges at any one time.
digraph g {
//overlap=false // does not apply to dot
//margin="10" // does not help (me)
//esep=1.3 // does not apply to dot
