Usage

    }

    // Defining the chart
    JFreeChart chart = ChartFactory.createPieChart("", dataset, false, false, false);

    // Defining the chartPanel
    //final ChartPanel chartPanel = new ChartPanel(chart);
    //chartPanel.setPreferredSize(new java.awt.Dimension(350, 350));

    // Defining the plot

    // Specify the colors here
