the legend would normally wrap, see following working snippet,
using the options shown in the attached image
google.charts.load('current', {
callback: function () {
var container = document.getElementById('chart_div');
var chart = new google.visualization.PieChart(container);
var data = google.visualization.arrayToDataTable([
['Education', 'People'],
['less than high school', 10],
['high school', 10],
['college associate', 10],
]);
var options = {
width: '470',
height: '450',
chartArea: {
width: '80%',
height: '80%',
left: 100,
},
pieSliceTextStyle: {
color: 'white',
fontSize: '17.5'
},
colors: ['#90c458', '#ff7f66', '#ffce55', '#52c2e8']
};
chart.draw(data, options);
},
packages: ['corechart']
});
