In Apache TinkerPop's Gremlin3.

  g.V().match(
    as("cypher").hasLabel("QueryLanguage").out("queries").as("graphs"),
    as("user").out("uses").as("cypher"),
      where("user", within(["Oracle","Apache Spark", "Tableau", "Structr"])),
    as("openCypher").out('makesAvailable").as("cypher")).
      select("cypher").by("attributes")

The original query is sort of an odd query as you don't don't need all the unbound variables...

And if you want to use SPARQL over TinkerPop, just use a SPARQL->Gremlin Virtual Machine compiler. https://github.com/dkuppitz/sparql-gremlin
