You can define default values in order to avoid repetition: digraph g{ node[fillcolor=red]; barn; house; … node[fillcolor=green]; farm; … edge[color=red]; barn -> house; edge[color=green]; barn –> farm; house –> farm; } Real variables are not supported. A more complex workaround would be to use gvpr – graph pattern scanning and processing language. gvpr reads and … Read more
The current version of Graphviz.app does not contain the “external editor” button shown in rampion’s screenshot above – Or the Render/Stop buttons, and it has replaced the “settings” button with “attributes”. However, it can be used as described. I downloaded ‘graphviz-2.27.20101110.0545.pkg’ from http://graphviz.org/Download_macos.php. Note that there are several places to download various things which call … Read more
I thought this was an interesting question, so I made an example alluvial diagram using d3: http://nickrabinowitz.com/projects/d3/alluvial/alluvial.html And, because d3 is so good at animation, and I thought it would look cool, I made an animated version as well: http://nickrabinowitz.com/projects/d3/alluvial/alluvial-dynamic.html It doesn’t cover everything you might want, but hopefully it will provide some basis. The … Read more
Use the edge attribute statement, as stated in the DOT Language documentation. digraph graphname { subgraph clusterA { node [shape=plaintext,style=filled]; edge [arrowhead=normal,arrowtail=dot]; 1 -> 2 ; 2 -> 3 -> X2 -> 5; 6; 7; label = “A”; color=blue } }
It can be done using nodeA -> nodeB [style=invis]
digraph { A; B; C subgraph Rel1 { edge [dir=none, color=red] A -> B -> C -> A } subgraph Rel2 { edge [color=blue] B -> C C -> A } }
It is possible to group nodes in graphviz by putting them into a cluster. A cluster is a special kind of subgraph which certain layout engines (dot, fdp, …) support, and if supported, the nodes in a cluster will be drawn together. From the documentation: If the name of the subgraph begins with cluster, Graphviz … Read more

You should just use: A -> B [dir=both]
I have no alternative to your usage of dir, but i can make it slightly shorter, if you want horizontal alignment, use the rankdir property of graph, to force direction from left to right. digraph { rankdir=LR; a->b; c->a [dir=”back”]; }
