Figure 7.
The network diagram contains many circular labelled nodes connected by thin lines. Two large dense clusters appear, one on the left and one on the right, linked by a narrow central chain of nodes. Smaller connected groups appear near the lower left of the left cluster. Three isolated nodes sit below the centre with no visible links. Nodes use different colours matched to a legend. The legend lists one to five years, six to 10 years, 11 to 15 years, and 16 to 20 years. Each node is labelled with an e number.AHP vectors similarity graph (by seniority)
