Extjs 4 have chart library . You need to create a service that will return XML or json. Create store and add a store to graph.

In order to take data from yahoo (not from Google yet) I created component in C# You can read it in my blog http://gregnozik.blogspot.com/2011/09/yahoo-finance-api.html

After you create a store you create a chart

var lineChart = new Ext.chart.LineChart({   
    store: store,   
    xField: 'framework',   
    yField: 'users'  
});
