How to place things differently in dot

How to place things differently in dot

I was asked to make a diagram and was thinking that dot in org-mode could
be a good idea.

I got reasonably fast the following:
​    #+BEGIN_SRC dot :file test.svg :cmdline -Kdot -Tsvg
    graph {
      utilities [label = "Utility's"]

      A
      B
      C

      D
      E
      F [shape = rectangle]


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

      G
      H
      I

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

      {rank = same; D, E, F}


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

      F -- E

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


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

This is a good deal in the right direction, but a few things should be
different:
​- E should be left of F
- resource should go to the second 'line' without losing its border
- K should be a 'line' lower

Are those things possible?

As attachment how it looks now.

If you do want to use dot, I have only ever managed to get what I want
by changing the order in which I specify the connections and/or more use
of sub-graphs.

Or perhaps ditaa.

​​It is certainly quick. ​I wait if they find it acceptable: if not I can
always check-out tikz or ditaa.

As a last resort, you can edit the svg file.

​It did cross my mind, but I am afraid it is not a real option (for me).

​I looked at ditaa and tikz. Especially ditta is very nice. It has document
and database elements, but it would also a lot more work to create and
especially to maintain. So I hope my dot version is acceptable.

Maybe this will help although it's not a complete implementation of
what you have. The idea is to define rows and arrange your nodes into
those rows by using rank=same. Then make the row nodes and edges
invisible. It's also important to do the sequencing correctly, e.g.
in your example, if you just switch F -- E to E -- F, E will be to the
left of F as you want. But I don't know how to get the resources
subgraph to be treated as a node and thereby place it on the same row as F.

In any case, here's the current trial balloon:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC dot :file test2.svg :cmdline -Kdot -Tsvg
graph foo {
row1--row2--row3--row4 [style="invisible"];
row1, row2, row3, row4 [style="invisible"];

utilities [label = "Utilities"]
 A
 B
 C
 D
 E
 F [shape="rectangle"]
 G
 H
 I
 K
 subgraph cluster_ta {
 color=blue
 {rank = same; L, M;}
 L
 M
 }

{rank=same; row1 utilities A B C; }
{rank=same; row2 D E F;}
{rank=same; row3 G H I;}
{rank=same; row4 K;}

subgraph cluster_resources {
  resources [label = "Resources"]
  graph[color=red];
 }

A -- F
B -- F
C -- F
A -- D
E -- F
F -- G
F -- H
F -- I
F -- K
K -- L
K -- M
L -- M
}
#+END_SRC

--8<---------------cut here---------------end--------------->8---

Nick

​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.​

Just put I after K and the subgraph.

You can make the rows be of size 0:

--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC dot :file test2.svg :cmdline -Kdot -Tsvg
graph foo {
row1--row2--row3--row4 [style="invis", fixedsize="true", width="0", height="0"];
row1, row2, row3, row4 [style="invis", fixedsize="true", width="0", height="0"];
...
--8<---------------cut here---------------end--------------->8---

​That works. It is even better when I put both H and I after it.

I also found a way to get resources at the correct place.

It know becomes:
    #+BEGIN_SRC dot :file test.png :cmdline -Kdot -Tpng
    graph {
      A
      B
      C
      utilities [label = "Utility's"]

      D
      E
      F [shape = rectangle]


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

      G
      G_ [style="invisible"]

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

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


      A -- F
      B -- F
      C -- F
      A -- D
      utilities -- resources [style="invisible"]

      E -- F

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

      G -- G_ [style="invisible"]

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

That looks very good indeed: I think I do not need to start working with
ditaa. :-)

​Everyone thanks for the help.​

​I changed to a digraph:
    #+BEGIN_SRC dot :file test.png :cmdline -Kdot -Tpng
    digraph {
      A
      B
      C
      utilities [label = "Utility's"]

      D
      E
      F [shape = rectangle]


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

      G
      G_ [style="invisible"]

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

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


      A -> F
      B -> F
      C -> F
      A -> D
      utilities -> resources [style="invisible"]

      E -> F

      F -> K [dir = back]
      F -> G [dir = back]
      F -> H [dir = back]
      F -> I [dir = back]

      G -> G_ [style="invisible"]

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

There is only one problem: I see the arrowhead with:
    utilities -> resources
and:
    'G -> G_'

Is there a way to get rid of those?

​I found that also:
