title: Trying to D3.nest only part of my csv data
body: <p>I have this csv text file, and I am trying to make an array, so that the array has an object for each name (d.name) and the values of the array are the # of people, and Date.</p>
  
  <p>Here is my data for example, </p>
  
  <blockquote>
    <p>Series    Name Date   People SMS12000003000000001 Joe  1990-01-01 200
    SMS12000003000000001  Don  1990-02-01 252 SMS12000003000000001    John
    1990-03-01    336 SMS12000003000000001    Bob  1990-04-01 112</p>
  </blockquote>
  
  <p>And all I want is my new d3 nested array to look like </p>
  
  <p>Object
       Key: Name
  and then the values be date and people.</p>
  
  <p>Currently my code is, </p>
  
  <pre><code>var newarray= 
      d3.nest()
          .key(function(d) { return d.Name;})
          .entries(data);
  
  console.log(newarray);
  </code></pre>
  
  <p>I also tried map, using a function(d) and returning d.people and d.date</p>
