nodos grupales con subgrafos

Question

Me gustaría agrupar algunos nodos con el siguiente código

digraph dataflow {
    subgraph pipeline {
        relations;
        synonyms;
        articles;
    }
    subgraph lucene {
        index;
        search;
    }
    training_data - > index;
    relations - > search;
    synonyms - > index;
    articles - > index;
    training_data - > evaluation;
}

Pero a dot no le importan los subgrafos:

Answer 1

Intente prefijar sus subgrafos con ''cluster_'':

digraph dataflow {
    subgraph cluster_pipeline {
        relations;
        synonyms;
        articles;
    }
    subgraph cluster_lucene {
        index;
        search;
    }
    training_data -> index;
    relations -> search;
    synonyms -> index;
    articles -> index;
    training_data -> evaluation;
}
