                 QtCommercial Charts QML API is an intuitive and simple way to show charts in your QML
                 applications. The following example QML shows you how to create a simple pie chart:

                 \class QPieSlice
                 \brief Defines a slice in pie series.
                 This object defines the properties of a single slice in a QPieSeries.
                 In addition to the obvious value and label properties the user can also control
                 the visual appearance of a slice. By modifying the visual appearance also means that
                 the user is overriding the default appearance set by the theme.
                 Note that if the user has customized slices and theme is changed all customizations will be lost.
                 To enable user interaction with the pie some basic signals are provided about clicking and hovering.

+                \snippet ../examples/qmlpiechart/qml/qmlpiechart/main.qml 4
