//so there's two divs on the page for this to select
d3.select('body')
    .selectAll('div')
    .data(["hello","there","world"])
    //this will map "hello" and "there" to the only two divs
    .html(function(d){return d;})
    //but theres 3 pieces of data...?
    //this is why d3 has the enter() function
    //think of it as "withTheLeftOverDataAfterMapping()" instead of "enter()"
    .enter()

This is how I configured the deploy of my rails apps to AWS Elastic Beanstalk through CircleCI 1.0.

If you are using the Circle CI 2.0, take a look at this article from ryansimms

Configure Environments Variables

On Project Settings > Environment Variables add this keys:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
  The aws user must have the right permissions. This can be hard, maybe, this can help you.
