neato: avoid edge overlaps
Using neato with fixed positions, is there a chance to avoid overlaps as you can see from edge from 1 to 7, although overlap is set to false?
digraph workflowGraph {
size="10,10"
graph [ splines="true" forcelabels="true" pad="1,0.25" nodesep="2" overlap="false" bgcolor="white" ];
node [ style="solid" shape="box" fontname="Arial" fontsize="14" fontcolor="black" ];
node [ pos="2,1!" ]; 1;
node [ pos="2,2!"]; 2;
node [ pos="1,3!" ]; 3;
node [ pos="3,3!" ]; 4;
node [ pos="2,3!" ]; 5;
node [ pos="2,4!"]; 6;
node [ pos="3,4!"]; 7;
1 -> 2
2 -> 3
2 -> 4
3 -> 5
5 -> 6
2 -> 5
4 -> 7
1 -> 7
}
