dbpedia describes this with very well with an example.

How many pointers to web pages are loaded in the triple store? (results):

PREFIX foaf: <http://xmlns.com/foaf/0.1/>

SELECT ?graph count(*) as ?count
WHERE {
  GRAPH ?graph {
    ?uri foaf:isPrimaryTopicOf ?page
  }
  filter (?uri != ?page) # This is just to make a point, they are never equal.
} GROUP BY ?graph ORDER BY desc(?count)
