scatter chart

A scatter chart is used to map correlation between sets of numbers.

function drawChart() {
	var data = google.visualization.arrayToDataTable([
	 [\'Age\', \'Weight\'],
	 [ 8,      12],
	 [ 4,      5.5],
	 [ 11,     14],
	 [ 4,      5],
	 [ 3,      3.5],
	 [ 6.5,    7]
	]);

	var options = {
	 title: \'Age vs. Weight comparison\',
	 hAxis: {title: \'Age\', minValue: 0, maxValue: 15},
	 vAxis: {title: \'Weight\', minValue: 0, maxValue: 15},
	 legend: \'none\'
	};

	var chart = new google.visualization.ScatterChart(document.getElementById(\'chart_div\'));
	chart.draw(data, options);
}
