以下是顯示圓餅圖的簡單網頁範例：
您可以將下列程式碼片段複製到電腦上的 .html 檔案，然後在瀏覽器中開啟檔案，以便顯示上方的圓餅圖：
<html>
<head>
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
// Load the Visualization API and the corechart package.
google.charts.load('current', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
</body>
</html>
長條圖如何？
如要將圓餅圖轉換為長條圖，請在程式碼中將 google.visualization.PieChart 替換為 google.visualization.BarChart，然後重新載入瀏覽器。您可能會發現「Slices」圖例遭到截斷。如要修正這個問題，請將 width 從 400 變更為 500、儲存檔案，然後重新載入瀏覽器。
