Sgvizler - renders SPARQL results in visualization

http://code.google.com/p/sgvizler/

Include charts your web pages simply by adding html element of the following form to your page:
 <div id="sgvzl_example1"
      data-sgvizler-endpoint="http://sws.ifi.uio.no/sparql/npd"
      data-sgvizler-query="SELECT ?class (count(?instance) AS ?noOfInstances)
                          WHERE{ ?instance a ?class }
                          GROUP BY ?class
                          ORDER BY ?class"
      data-sgvizler-chart="gPieChart"
      style="width:800px; height:400px;"></div> 


To cite Sgvizler, use the following reference: "Martin G. Skjæveland. 
Sgvizler: A JavaScript Wrapper for Easy Visualization of SPARQL Result 
Sets. ESWC 2012. Demo paper." The paper is yet to be published in the 
workshop/poster/demo proceedings of ESWC 2012, but it is available on 
the ESWC 2012 website, the poster is also available.
