    // Set the pyramid data and labels
    c->setData(DoubleArray(data, (int)(sizeof(data) / sizeof(data[0]))), StringArray(labels, (int)(
        sizeof(labels) / sizeof(labels[0]))));

    // Add labels at the center of the pyramid layers using Arial Bold font. The labels will have
    // two lines showing the layer name and percentage.

    // Output the chart
