digraph blah { "a" -> "b"; "a" -> "c"; "b" -> "d"; "c" -> "d"; }
Try to overflow horizontally, and see what happens. Do we scroll?
digraph blah { "root" -> "00"; "root" -> "01"; "root" -> "02"; "root" -> "03"; "root" -> "04"; "root" -> "05"; "root" -> "06"; "root" -> "07"; "root" -> "08"; "root" -> "09"; "root" -> "10"; "root" -> "11"; "root" -> "12"; "root" -> "13"; "root" -> "14"; "root" -> "15"; "root" -> "16"; "root" -> "17"; "root" -> "18"; "root" -> "19"; "root" -> "20"; "root" -> "21"; "root" -> "22"; "root" -> "23"; "root" -> "24"; "root" -> "25"; "root" -> "26"; "root" -> "27"; "root" -> "28"; "root" -> "29"; "root" -> "30"; "root" -> "31"; "root" -> "32"; "root" -> "33"; "root" -> "34"; "root" -> "35"; "root" -> "36"; "root" -> "37"; "root" -> "38"; "root" -> "39"; }
