Sid, See this staging edition of DBpedia at: http://dbpedia2.openlinksw.com:8895/fct . Also look at: http://dbpedia2.openlinksw.com:8895/void/page/Dataset . Each subset represents a Named Graph under the Graph Grp. <http://dbpedia.org>, so <http://dbpedia.org/void/http://dbpedia.org/categories_label_en/Stat> is the stats associated with Named Graph: <http://dbpedia.org/categories_label_en> If you go via /fct, you can also use the "statistics" link to expose all the Named Graphs that reference an Entity, ditto its soure Graphs.
