title: getImageURI() not work from orgchart by google
body: <p><a href="https://jsfiddle.net/ei06039/b8bq4pvy/" rel="nofollow">Fiddle</a></p>
  
  <p>I created this fiddle but when try <code>getImageURI()</code> from chart (orgchart google charts) one error is generated.</p>
  
  <blockquote>
    <p>ERROR: "Uncaught TypeError: chart.getImageURI is not a function"</p>
  </blockquote>
  
  <p>I need to generate an image or a PDF from orgchart created. Is it possible?</p>
  
  <pre><code>google.charts.load('current', {packages:["corechart","orgchart"]});
  google.charts.setOnLoadCallback(drawChart);
  
  function drawChart() {
      var data = new google.visualization.DataTable();
      data.addColumn('string', 'Name');
      data.addColumn('string', 'Manager');
      data.addColumn('string', 'ToolTip');
  
      // For each orgchart box, provide the name, manager, and tooltip to show.
      data.addRows([
        [{v:'Mike', f:'Mike&lt;div style="color:red; font-style:italic"&gt;President&lt;/div&gt;'},
         '', 'The President'],
        [{v:'Jim', f:'Jim&lt;div style="color:red; font-style:italic"&gt;Vice President&lt;/div&gt;'},
         'Mike', 'VP'],
        ['Alice', 'Mike', ''],
        ['Bob', 'Jim', 'Bob Sponge'],
        ['Carol', 'Bob', '']
      ]);
  
      // Create the chart.
      var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));
  
      google.visualization.events.addListener(chart, 'ready', function () {
          $( "#chart_div2" ).append( '&lt;img src="' + chart.getImageURI() + '"&gt;' );
      });
      // Draw the chart, setting the allowHtml option to true for the tooltips.
      chart.draw(data, {allowHtml:true});
  }
  </code></pre>
