Can the user choose node names?

[jchia]

If I understand the documentation correctly, there is no way to name nodes in a graph. E.g. I cannot have a graph like this:

digraph G {
    A;
    B;

    A -> B;
}

This is because there is no function that produces a NodeId for a given node name. Consequently generated graphs have generic names automatically assigned by dotgen.

Is my understanding correct? If so, this seems like a major drawback since users commonly want to decide the names shown for the nodes in their graphs.
