<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);

¿Qué te parece un gráfico de barras?
Para convertir el gráfico circular en un gráfico de barras, reemplaza google.visualization.PieChart por google.visualization.BarChart en el código y vuelve a cargar el navegador. Es posible que notes que la leyenda "Slices" (Secciones) está truncada. Para solucionar este problema, cambia width de 400 a 500, guarda el archivo y vuelve a cargar el navegador.

You\nmay notice that the \"Slices\" legend is truncated. To fix this, change `width` to 500\nfrom 400, save the file, and reload your browser. \n[**Next: *How does it\nwork?***](/chart/interactive/docs/basic_load_libs)"]]
