I did a little search for a jQuery plugin that can do the job and I found DynaCloud.
You can include a Tag Cloud on your page in 4 steps.
1) Add on your page a container for the tag cloud. For good results create an HTML Region and put the following code in the region source. (Set the template to Sidebar Region)
<div id="dynacloud" style="font-size:12px;"></div>
2) Load jQuery using Google AJAX Libraries API
<script src="http://www.google.com/jsapi"></script>
<script>
// Load jQuery
google.load("jquery", "1.2.6", {uncompressed:false});
</script>
3) Load DynaCloud Plugin
<script src="&WORKSPACE_IMAGES.jquery.dynacloud-4.js"></script>
4) Add CSS styles to display the Tag Cloud
<style type="text/css">
div#dynacloud {
font-size:5px;
}
div#dynacloud a span{
font-size:1em;
}
.highlight { background-color: yellow }
</style>
5) Configure the settings of DynaCloud. When the page his loaded, add the CSS class "dynacloud" to your page reports regions. And finally, generate the tag cloud.
<script>
$.dynaCloud.sort = false;
$().ready(function() {
$('.t4ReportsRegion').addClass("dynacloud");
$('.dynacloud').dynaCloud();
});
</script>
You can see my working example of a Tag Cloud in APEX.
Talking about clouds, here in Montreal it's snowing... they announced 15-30cm of snow for today. Tonight traveling back home will be long! ;)
