Code Example: Google Charts Pie Chart

Here's a functioning code example of how to make a PDF that uses a Google Chart Pie Chart:
<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
      google.charts.load('current', {'packages':['corechart']});
      google.charts.setOnLoadCallback(drawChart);
      function drawChart() {

        var data = google.visualization.arrayToDataTable([
          ['Task', 'Hours per Day'],
          ['Work',     11],
          ['Eat',      2],
          ['Commute',  2],
          ['Watch TV', 2],
          ['Sleep',    7]
        ]);

        var options = {
          title: 'My Daily Activities'
        };

        var chart = new google.visualization.PieChart(document.getElementById('piechart'));

        chart.draw(data, options);
      }
    </script>
    <script type="text/javascript">
      var didWait = false;
      // DocRaptor polls docraptorJavaScriptFinished until it is true
      docraptorJavaScriptFinished = function() {
        if (! didWait) {
          setTimeout(function(){
            didWait = true;
          }, 10000);
          return false;
        }
        document.body.appendChild(document.createTextNode("JavaScript inserted this text."));
        return true;
      }
    </script>
  </head>
  <body>
    This is an example Google Charts Pie Chart.
    <div id="piechart" style="width: 900px; height: 500px;"></div>
  </body>
</html>
