I’m explaining this badly I think. But let’s say a node has links to and from it. The same exact ones going to and from it, in the same amount, or in a statistically significant percentage, except in a completely different node. But the two nodes do not connect to each other. So having a way to visually detect these. Maybe like colored lines. So you can see a statistical correlation.
I use the plugin graph analysis to find correlations between nodes
