Each cell is the relationship score between two members, numbered as in the Indicators table above. Hover a cell for the domains and the signals behind it.
2 of 3 possible pairs are directly linked. A blank cell only means those two are not linked directly, they can still belong to the cluster through a third member. A greyed-out cell is linked below the clustering threshold or by same-kit similarity - it did not form this cluster.
