title: How to create new line in Plot.ly JS title
body: <p>I am using the <a href="https://plot.ly/javascript/" rel="noreferrer">Plot.ly JS</a> for graphs. The graphs are charting the answers given to certain questions in a survey. So, the title of the graph is the question itself which can get a little long. Right now, the title runs off the graph and is hidden as seen in the image below (can't embed images yet on Stack Overflow so it created a link to the image instead):</p>
  
  <p><a href="https://i.stack.imgur.com/PEaNV.png" rel="noreferrer"><img src="https://i.stack.imgur.com/PEaNV.png" alt="Plotly title example image"></a></p>
  
  <p>This is the code being called where <code>values</code> and <code>labels</code> are variables defined elsewhere:</p>
  
  <pre><code>var graph_data = [
      {
          values: values,
          labels: labels,
          type: 'pie'
      }
  ];
  var layout = {
   title: 'How responsive has our support team been to your questions or concerns?'
  };
  Plotly.newPlot( chartID, graph_data, layout );
  </code></pre>
  
  <p>I tried adding new line characters into the string such as <code>\r</code> and <code>\n</code> and <code>\r\n</code> and it did not work. I also tried changing the CSS property of word-wrap and it did not work. Any advice to easily show the title on multiple lines in Plot.ly JS?</p>
