#include "chartdir.h"

int main(int argc, char *argv[])

    // The labels for the pie chart
    const char *labels[] = {"Labor", "Licenses", "Taxes", "Legal", "Insurance", "Facilities",

    // Create a PieChart object of size 360 x 300 pixels
    PieChart *c = new PieChart(360, 300);

    // Set the center of the pie at (180, 140) and the radius to 100 pixels
    c->setPieSize(180, 140, 100);

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

    // Output the chart

    //free up resources
    delete c;
    return 0;
