Trouble displaying chart: Incompatible class change error

Hello, I'm having trouble displaying dCharts in my application. Whenever I add my chart to a layout using the addComponent() method, I end up with the same error: IncompatibleClassChangeError.
Here is my code for the page:
 

public class GCContentView extends VerticalLayout implements View{

public GCContentView(){

DataSeries dataSeries = new DataSeries()
.add(2, 6, 7, 10);

SeriesDefaults seriesDefaults = new SeriesDefaults()
.setRenderer(SeriesRenderers.BAR);

Axes axes = new Axes()
.addAxis(
new XYaxis()
.setRenderer(AxisRenderers.CATEGORY)
.setTicks(
new Ticks()
.add("a", "b", "c", "d")));

Highlighter highlighter = new Highlighter()
.setShow(false);

Options options = new Options()
.setSeriesDefaults(seriesDefaults)
.setAxes(axes)
.setHighlighter(highlighter);

DCharts chart = new DCharts()
.setDataSeries(dataSeries)
.setOptions(options)
.show();

addComponent(chart);
}

@Override
public void enter(ViewChangeEvent event) {

}
}

I have tried other charts addons like HighCharts and chart.js but I keep getting the same error.
