Watch the CPU and Memory gauges for a second here:
http://code.google.com/apis/visualization/documentation/gallery/gauge.html#Loading

they move dynamically.

My question - the example code shown below there does not move the gauges like that (or at least when I tried it in my own project.)

Does anyone know how to get it moving dynamically like that?

(Also, will these gauges slow down my site connecting to Google? On the other hand, will it bring up my rankings?)

Thanks!

The example code and the actual demo are different. Try this instead:

<html>
  <head>
    <script type='text/javascript' src='http://www.google.com/jsapi'&gt;&lt;/script&gt;
    <script type='text/javascript'>
      google.load('visualization', '1', {packages:['gauge']});
      google.setOnLoadCallback(drawChart);
    </script>
  </head>

  <body>
    <div id='chart_div'></div>
    <script type="text/javascript">
  function Timer(){this.t={};this.tick=function(a,b){this.t[a]=[(new Date).getTime(),b]};this.tick("start")}var loadTimer=new Timer;window.jstiming={Timer:Timer,load:loadTimer};if(window.external&&window.external.pageT)window.jstiming.pt=window.external.pageT;if(window.jstiming)window.jstiming.report=function(g,d){var c="";if(window.jstiming.pt){c+="&srt="+window.jstiming.pt;delete window.jstiming.pt}if(window.external&&window.external.tran)c+="&tran="+window.external.tran;var a=g.t,h=a.start;delete a.start;var i=[],e=[];for(var b in a){if(b.indexOf("_")==0)continue;var f=a[b][1];if(f)a[f][0]&&e.push(b+"."+(a[b][0]-a[f][0]));else h&&i.push(b+"."+(a[b][0]-h[0]))}if(d)for(var j in d)c+="&"+j+"="+d[j];(new Image).src=["http://csi.gstatic.com/csi?v=3","&amp;s=gviz&amp;action=",g.name,e.length?"&amp;it="+e.join(",")+c:c,"&amp;rt=",i.join(",")].join("")};
</script>

<script type="text/javascript">

var csi_timer = new window.jstiming.Timer();
csi_timer.name = 'docs_gauge';

google.setOnLoadCallback(drawChart);

function drawChart() {

  csi_timer.tick('load');

  var data = new google.visualization.DataTable();
  data.addColumn('string', 'Label');
  data.addColumn('number', 'Value');
  data.addRows(3);
  data.setValue(0, 0, 'Memory');
  data.setValue(0, 1, 80);

  var chart = new google.visualization.Gauge(document.getElementById('chart_div'));

  csi_timer.tick('new');

  var options = {width: 400, height: 120, redFrom: 90, redTo: 100,
      yellowFrom:75, yellowTo: 90, minorTicks: 5};
  chart.draw(data, options);

  csi_timer.tick('draw');
  window.jstiming.report(csi_timer);  

  setInterval(function() {
    data.setValue(0, 1, 40 + Math.round(60 * Math.random()));
    chart.draw(data, options);
  }, 13000);
  setInterval(function() {
    data.setValue(1, 1, 40 + Math.round(60 * Math.random()));
    chart.draw(data, options);

  setInterval(function() {

    chart.draw(data, options);
