Too little labels are visible at the default-zoom version.
At least all the blue nodes labels should be visible.
And since the network only contains a few dozen nodes, I think it should be possible to visualize most labels at the default-zoom version.
To avoid overlapping, open the network in Gephi. Use the 'label adjust' spatialisation algorithm and then move manually the nodes a little bit.
