Insert JavaScript

Hi,

ich created a Google map using a generator and I would like to insert it on a custom page. I tried to insert his in the “Text” area when you edit a page but without success.
The code itself is working fine, tried it with a WYSIWYG editor and it will show the map correctly.

This is the code:

<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>google.load('visualization', '1', {'packages': ['geochart']});
google.setOnLoadCallback(drawVisualization);

  function drawVisualization() {var data = new google.visualization.DataTable();

 data.addColumn('string', 'Country');
 data.addColumn('number', 'Value');
 data.addColumn({type:'string', role:'tooltip'});var ivalue = new Array();

 data.addRows([[{v:'New York',f:'New York'},0,'']]);
 ivalue['New York'] = '';

 data.addRows([[{v:'Washington D.C.',f:'Washington D.C.'},1,'']]);
 ivalue['Washington D.C.'] = '';

 data.addRows([[{v:'San Francisco',f:'San Francisco'},2,'']]);
 ivalue['San Francisco'] = '';

 data.addRows([[{v:'Los Angeles',f:'Los Angeles'},3,'']]);
 ivalue['Los Angeles'] = '';

 data.addRows([[{v:'Las Vegas',f:'Las Vegas'},4,'']]);
 ivalue['Las Vegas'] = '';

 var options = {
 backgroundColor: {fill:'',stroke:'#FFFFFF' ,strokeWidth:0 },
 colorAxis:  {minValue: 0, maxValue: 4,  colors: ['#0011FF','#0011FF','#0011FF','0011FF','0011FF',]},
 legend: 'none',
 backgroundColor: {fill:'',stroke:'#FFFFFF' ,strokeWidth:0 },
 datalessRegionColor: '#f5f5f5',
 displayMode: 'markers',
 enableRegionInteractivity: 'false',
 resolution: 'provinces',
 sizeAxis: {minValue: 1, maxValue:1,minSize:4,  maxSize: 4},
 region:'US',
 keepAspectRatio: true,
 width:600,
 height:400,
 tooltip: {textStyle: {color: '#444444'}, trigger:'focus'}
 };
  var chart = new google.visualization.GeoChart(document.getElementById('visualization'));
 chart.draw(data, options);
 }
 </script>
 <div id='visualization'></div>

Any idea?

Thanks in advance
Moritz
