nodesep
In
dot, nodesep specifies the minimum space between two adjacent nodes in the same rank, in inches
type: double, default: 0.25, minimum: 0.02
For other layouts, nodesep affects the spacing between loops on a single node, or multiedges between
a pair of nodes.
Small node separation
digraph {
nodesep=0.1;
node1; node2; node3;
}
Large node separation
digraph {
nodesep=0.5;
node1; node2; node3;
