Code snippet: SPARQL Query Graph Density

Code snippet: SPARQL Query Graph Density

I’m testing out sharing SPARQL code snippets using Github Gist features. I’ll be adding more as I work through more graph-specific examples using SPARQLverse, but here is my first one:

 SELECT (?nrEdges/(?nrNodes *(?nrNodes - 1.0)) AS ?graphDensity)
 FROM <graphName>
 WHERE {
  { SELECT (COUNT (*) AS ?nrEdges) (COUNT (DISTINCT ?person) AS ?nrNodes)
    WHERE { ?person <knows> ?anotherPerson . }
   }
 }

Ideally we’d have a common landing place for building up a library of these kinds of examples.
