Tag Clouds for Blogger

I found this useful tag cloud for blogger.

Simple Tag Cloud Widget for Blogger

I've replicated the code below just in case the above link does not work. All you need to do is add a label widget and change its code to the following:

   1: <b:widget id='TagCloud' locked='false' title='Tags' type='Label'>
   2:     <b:includable id='main'>
   3:     <b:if cond='data:title'>
   4:       <h2><data:title/></h2>
   5:     </b:if>
   6:     <div class='widget-content' style='text-align: justify;'>
   7:          <script type="text/javascript">

  14:         //Variables:

Note to self!! Do not use quotes in the labels as it screws up the code.
