      var geomap = new google.visualization.GeoMap(

    }


    google.setOnLoadCallback(drawVisualization);

</head>
<body style="font-family: Arial;border: 0 none;">
<div id="visualization" style="width: 800px; height: 400px;"></div>
</body>
</html>

instead of displaying a map of the entire world i would like to know how to display just the US?

From your example, set the region option on the geomap:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <title>Google Visualization API Sample</title>
  <script type="text/javascript" src="http://www.google.com/jsapi"></script>
  <script type="text/javascript">
    google.load('visualization', '1', {packages: ['geomap']});

    function drawVisualization() {
      var data = new google.visualization.DataTable();
      data.addRows(6);
      data.addColumn('string', 'Country');
      data.addColumn('number', 'Popularity');
      data.setValue(1, 0, 'United States');
      data.setValue(1, 1, 300);

      var geomap = new google.visualization.GeoMap(
          document.getElementById('visualization'));

      var options = { region: 'us_metro' };
      geomap.draw(data, options);
    }


    google.setOnLoadCallback(drawVisualization);
  </script>
</head>
<body style="font-family: Arial;border: 0 none;">
<div id="visualization" style="width: 800px; height: 400px;"></div>
</body>
</html>

Not quite sure why you are setting the popularity of other countries to just center on the US though.
