JavaFx - CHART example

We would like to have a chart of the imported fruits. 

Let' see in JavaFx the PieChart diagram:

public class JavaFXApplication1 extends Application {

    public static void main(String[] args) {
        launch(args);
    }
   
    @Override
    public void start(Stage primaryStage) {
       
      primaryStage.setTitle("Chart example");
      ObservableList<PieChart.Data> pieChartData = FXCollections.observableArrayList(
                new PieChart.Data("Grapefruit", 13),
                new PieChart.Data("Oranges", 25),
                new PieChart.Data("Plums", 10),
                new PieChart.Data("Pears", 22),
                new PieChart.Data("Apples", 30));
        PieChart chart = new PieChart(pieChartData);
        chart.setTitle("Imported Fruits");       
       
        StackPane root = new StackPane();
        root.getChildren().add(chart);
        primaryStage.setScene(new Scene(root, 300, 250));
        primaryStage.show();
               
    }
}
