title: Delay for every element with RXJS
body: <p>I'm using RxViz to simulate different actions that comes every 1 sec. When I try</p>
  
  <pre><code>Rx.Observable.create(obs =&gt; {
    obs.next([1, 2, 3]); // or could be ['aaa', 'bbbb', 'ccc']
    obs.complete();
  }).delay(1000);
  </code></pre>
  
  <p>on <a href="https://rxviz.com" rel="noreferrer">https://rxviz.com</a> </p>
  
  <p>or on my own with a console.log</p>
  
  <p>it keeps displaying the three number 1, 2, 3 at the same time</p>
  
  <p>There's a post about this same problem, but none of the answer works for me. I'm using Rx last version 6</p>
