Here's an example of HTML code using Google Charts API to display a column chart comparing the population growth rate of America, Germany, China, and India:

```
<!DOCTYPE html>
<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([
          ['Country', 'Population Growth Rate'],
          ['America',  1.05],
          ['Germany',  0.25],
          ['China',  0.7],
          ['India',  1.2]
        ]);

        var options = {
          title: 'Population Growth Rate in Different Countries',
          chartArea: {width: '50%'},
          hAxis: {
            title: 'Population Growth Rate',
            minValue: 0
          },
          vAxis: {
            title: 'Country',
            textStyle: {
              fontSize: 12
            }
          }
        };

        var chart = new google.visualization.BarChart(document.getElementById('chart_div'));

        chart.draw(data, options);
      }
    </script>
  </head>
  <body>
    <div id="chart_div"></div>
  </body>
</html>
```

Replace the values with the actual population growth rate numbers for each country.
America, Germania, Cina, India
