I am trying to link in Dygraphs (javascript native graphing library) into smartGWT 2.2. I have successfully compiled and linked my project to the javascript library. I am getting the following error:

 

23:36:32.818:WARN:Log:(TypeError): $wnd.google is undefined
 stack: ...

I am not sure what the error means or what I need to do to resolve. Here is my .java code as well:

public class Dygraphs implements EntryPoint {

	@Override
	public void onModuleLoad() {
		final VLayout main = new VLayout();
		
		
		main.setWidth100();
		main.setHeight100();
		
		
		ToolStrip topBar = new ToolStrip();
		
		topBar.setHeight(33);
	    topBar.setWidth100();
        topBar.addSpacer(6);
		
		
        
        ToolStripButton devConsoleButton = new ToolStripButton();
	        devConsoleButton.setTitle("Developer Console");
	        devConsoleButton.addClickHandler(new com.smartgwt.client.widgets.events.ClickHandler() {
	            public void onClick(ClickEvent event) {
	                SC.showConsole();
	                
	                
	                
	            }
	        });

	        topBar.addButton(devConsoleButton);

	        HLayout hLayout = new HLayout();
		    hLayout.setLayoutMargin(5);
		    hLayout.setWidth100();
		    hLayout.setHeight100();
		    hLayout.setShowEdges(true);
		
	        
	        
	    main.addMember(topBar);
		main.addMember(hLayout);
		
	    try {
			drawDygraph(hLayout.getElement(),createData());
		} catch (Exception e) {
			SC.logWarn(e.getMessage());
		}


		
		main.draw();
		
		
		
	}

	
	// Protected because the GWT compiler has to generate a subclass.
	  protected interface Resources extends ClientBundle {
	    @Source("com/test/client/dygraph-combined.js")
	    TextResource dygraphs();
	  }
