In the case of closeness centrality, or average shortest path length, lower values indicate more central nodes. Thus, since node D’s closeness centrality is 1.71 and node A’s is 3.43, node D is more central by this measure.
The benefits of closeness centrality are that it indicates nodes as more central if they are closer to most of the nodes in the graph. This strongly corresponds to visual centrality—a node that would appear toward the center of a graph when we draw it usually has a high closeness centrality.
