​I did it a little differently:
    #+BEGIN_SRC dot :file test.png :cmdline -Kdot -Tpng
    graph {
      utilities [label = "Utility's"]

      A
      B
      C

      D
      E
      F [shape = rectangle]


      subgraph cluster_resources {
        color=blue
        resources [label = "Resources"]
      }

      G
      G_ [style="invisible"]
      H
      I

      K
      subgraph cluster_ta {
        color=blue
        {rank = same; L, M}
        L
        M
      }

      {rank = same; D,  E, F}
      {rank = same; G_, K}


      A -- F
      B -- F
      C -- F
      A -- D

      E -- F

      F -- K
      F -- G
      F -- H
      F -- I

      G -- G_ [style="invisible"]

      K -- L
      K -- M
      L -- M
    }
    #+END_SRC
​

​In this way I do not get an empty column. It would be better when K would
put between and below H and I, but I think I can live with it.​
