No-overlapping edges with positioned nodes - graphviz

Question

No-overlapping option (overlap=false) and positioned ("-n2" command-line parameter) are incompatible.
strict graph {
overlap=false;
1 [label="", xlabel=<<FONT POINT-SIZE="7">1</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="120.4,31.1!"];
2 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">2</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="73,35.5!"];
3 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">3</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="236.2,35.2!"];
4 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">4</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,100!"];
5 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">5</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,90!"];
6 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">6</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,80!"];
1 -- 4 [arrowhead=none, shape=none];
2 -- 5 [arrowhead=none, shape=none];
3 -- 6 [arrowhead=none, shape=none];
}
when a execute the folloing command-line:
neato -n2 -Tpng -ographviz-overlap-test.png graphviz-overlap-test.dotty
I got the following result:
Do you know alternative solution to produce graph of nodes connected with no-overlapping edge?
Thanks in advance,

Answer 1

As long as you tell graphviz the exact position of the nodes, no chance to avoid overlaps with the code you are using. I have manually exchanged the position of nodes 1 and 2 and this way re-ordered the nodes. I guess you produce the dotty file with some other software, that's the culprit.
strict graph {
overlap=false;
1 [label="", xlabel=<<FONT POINT-SIZE="7">1</FONT>>,
shape=circle, style=filled, width=0.05, pin=true, pos="73,35.5!"];
# ^^^^^^^^^^^^^^
2 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">2</FONT>>,
shape=circle, style=filled, width=0.05, pin=true, pos="120.4,31.1!"];
# ^^^^^^^^^^^^^^^^^
3 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">3</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="236.2,35.2!"];
4 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">4</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,100!"];
5 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">5</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,90!"];
6 [label="", labelfontsize="5", xlabel=<<FONT POINT-SIZE="7">6</FONT>>, shape=circle, style=filled, width=0.05, pin=true, pos="350,80!"];
1 -- 4 [arrowhead=none, shape=none];
2 -- 5 [arrowhead=none, shape=none];
3 -- 6 [arrowhead=none, shape=none];
}
which produces
