title: GWT with Charts API example from Google not working
body: <p>I have downloaded <a href="http://code.google.com/p/gwt-google-apis/downloads/detail?name=gwt-visualization-1.1.0.zip&amp;can=2&amp;q=" rel="nofollow noreferrer">http://code.google.com/p/gwt-google-apis/downloads/detail?name=gwt-visualization-1.1.0.zip&amp;can=2&amp;q=</a> archive that comes with jar that is needed in order to use charts in GWT.
  In the archive is also example application (<a href="http://gwt.google.com/samples/hellovisualization-1.1.0/HelloVisualization.html" rel="nofollow noreferrer">http://gwt.google.com/samples/hellovisualization-1.1.0/HelloVisualization.html</a>). But this example is not working for me. It has an runtime error at this line:
        DataTable data = DataTable.create();</p>
  
  <p>Eclipse reports this:
  com.google.gwt.core.client.JavaScriptException: (TypeError): Cannot read property 'DataTable' of undefined.</p>
  
  <p>What is wrong here?</p>
