Hi.
I´m trying to do a simple chart using an external URL that returns a JSON:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<script type="text/javascript" src="
https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load('visualization', '1', {packages:['corechart']});
google.setOnLoadCallback(desenhaGrafico);
function desenhaGrafico() {
var wrapper = new google.visualization.ChartWrapper({
dataSourceUrl:'https://raw.github.com/caelum/caelum-online/master/google-chart-tools/07-dados.json',
chartType: 'AreaChart',
containerId: 'meu_grafico',
options:{width:900, height:300}
});
wrapper.draw();
}
</script>
</head>
<body>
<div id="meu_grafico"> </div>
</body>
</html>
You can check the existence of URL by browser.
I´ve tried other valid URLs, but the result is the same.
But I´m receiving the message
Request timed out
What can be?
Thanks in advance
