/**
 * @brief
 * This class abstracts the view of a pie series. This class is a kind of
 * CXTPChartSeriesView.
 *
 * @details
 * A pie chart (or a circle graph) is a circular chart divided into sectors,
 * illustrating percents. In a pie chart, the arc length of each sector (and
 * consequently its central angle and area), is proportional to the quantity
 * it represents. Together, the sectors create a full disk.
