Another interesting version of the diagram.
Good work.

However, it is a bit disappointing to see that the many sites at the rkbexplorer activity are treated as one node.
(Cathy Dolbear of the OS raised the strangeness of this quite a while ago on this list, in relation to connection from the Pub Guide appearing to be to things like dblp, and the complete lack of visibility of the AdminstrativeGeography data.)
In fact there are 39 often heavily interlinked sites on rkbexplorer.com, with external linkage links, as compared with 43 other sites on the whole LOD diagram.
The linkage can be found by querying individual domains for their void descriptions, or all the void descriptions can be found at void.rkbexplorer.com:

PREFIX rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX void:  <http://rdfs.org/ns/void#>
PREFIX scovo: <http://purl.org/NET/scovo#>
SELECT ?subjects ?objects ?stats  WHERE { ?crs void:subjectsTarget ?subjects . ?crs void:objectsTarget ?objects . ?crs void:statItem ?item . ?item rdf:value ?stats }

To http://void.rkbexplorer.com/sparql/ is a bit dirty but should do the trick.
