title: What are jquery (/javascript) treemaps? (ratio, datavisualization, area, zoomable,squares,rectangles,space,volume)
body: <p><a href="http://www.informationisbeautiful.net/visualizations/the-bbc-o-gram/%20stackexchange.com/sites#" rel="nofollow">Example</a></p>
  
  <p>I am about to make one or better an extented/custom version ( like for example world population:first continents boxes visible only and countries small within, then scroll/zoom in and even states, cities  become visible within the country boxes, etc., etc.  (can be animated/fading in or just static and completely loaded from the beginning since I prefer a thin solution and its a limited dataset)</p>
  
  <p>Yet I would know how to go for it with javascript or php only,
  but jquery sounds like good performance and writting far less code, 
  so I want to learn it for this.</p>
  
  <p>Do you know of a suitable jquery plugin?</p>
  
  <p>or else one of these <a href="http://en.wikipedia.org/wiki/List_of_treemapping_software" rel="nofollow">wikipedia/List_of_treemapping_software</a><br>
  or these  <a href="http://en.wikipedia.org/wiki/Data_visualization#Data_visualization_software" rel="nofollow">wikipedia/Data_visualization_software</a>? (and there .js exports)</p>
  
  <p>thanks!=)</p>
