the former social graph that we used on ECLAP has been improved to be used as stand along tool.
It can be easily used ad general tools for navigating on LOD, http://log.disit.org
as well as on a specific visualize of EDM LOD of europeana content as:
http://log.disit.org/service/index.php?uri=http://data.europeana.eu/proxy/provider/2022105/F5F8F40DCA36E201A24D84E0D11BD3563A63193A&sparql=http://europeana.ontotext.com/sparql
this means that almost all projects could embed the LOG visualizer
into their web pages...
