title: Write a Cypher query to CREATE links between random nodes
body: <p>To seed a database, I would like to create a small set of Person nodes...</p>
  
  <pre><code>WITH ["Amy","Bob","Cal","Dan","Eve"]
  AS names
  FOREACH (r IN range(0, size(names)-1) |
    CREATE (:Person {name: names[r]})
  )
  </code></pre>
  
  <p>... and I would like to create a random connection for each Person. Is it possible to do this in a single query?</p>
  
  <p>I imagine that I would need to add each new Person to a collection, and work with a variable created from FLOOR(RAND() * size(names)), but the official documentation does not give many clues as to how to do this.</p>
