Write your Cypher queries and navigate your graph

This query:

MATCH (vp:Person {name:"VLADIMIR PUTIN"}), (dt:Person {name:"DONALD J. TRUMP"})
MATCH path = allShortestPaths( (vp)-[*]-(dt) )
RETURN path

produces the following result_

%neo4j
MATCH (o:Organization)-[r]-()
RETURN o.name, count(*), collect(distinct type(r)) AS types
ORDER BY count(*) DESC
LIMIT ${Show top=10}

produces the following result:
