How do I position the label for subgraph cluster to appear at it's left instead of being centered?
digraph mygraph {
test1;
subgraph cluster_mysubgraph {
label = "This text should be at the left of the subgraph - not centered!";
test2;
test3;
test4;
test5;
test6;
test7;
}
test1 -> {test2, test3, test4, test5, test6, test7};
}
