[The following code is available in "cppdemo/simplepie". A MFC version of the code is available in "mfcdemo" (Windows edition only).]
#include "chartdir.h"

int main(int argc, char *argv[])
{
    // The data for the pie chart
    double data[] = {25, 18, 15, 12, 8, 30, 35};

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

    // 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, sizeof(data)/sizeof(data[0])), StringArray(labels,
        sizeof(labels)/sizeof(labels[0])));

    // output the chart
    c->makeChart("simplepie.png");

    //free up resources
    delete c;
    return 0;
