How to control the position of the nodes

Question

Just two short questions. Let's consider the following code from Graphviz:

digraph EXAMPLE {

splines="line";
node[shape=circle, fontname="Verdana"];
ranksep=1;

SC -> {00, 01} -> {02, 03} -> {FC}
SU -> {13, 12, 10} -> {11} -> {FU}
SD -> {22} -> {23, 21, 20} -> {FD}
ST -> {31, 32} -> {33, 30} -> {FT}

S -> {SC ; SU ; SD ; ST}
{FC ; FU ; FD ; FT} -> F

}

That is rendering the following:

I have two questions:

1. How can I make that node "11" appears in the same vertical level as node "12"?
2. How can attain that the horizontal distance between nodes "SC", "SU", "SD", and "ST" would be the same?

Thank you in advance!!

Answer 1

• Giving multiple nodes the same group (https://graphviz.org/docs/attrs/group/) value usually results on vertical (horizontal) edges
• Adding equal weight (https://graphviz.org/docs/attrs/weight/) values to the 4 nodes resulted in equidistant node layout. nodesep (https://graphviz.org/docs/attrs/nodesep/) could also be used, but it would affect all the node separations.

digraph EXAMPLE {

splines="line";
node[shape=circle, fontname="Verdana"];
ranksep=1;

{node [group=gA] 11 12 }
SC -> {00, 01} -> {02, 03} -> {FC}
SU -> {13, 12, 10} -> {11} -> {FU}
SD -> {22} -> {23, 21, 20} -> {FD}
ST -> {31, 32} -> {33, 30} -> {FT}

{
edge[weight=10]
S -> {SC ; SU ; SD ; ST}
}
{FC ; FU ; FD ; FT} -> F

}
