* \class QItemModelScatterDataMapping

* \brief Data model mapping for Q3DScatter.
* \since 1.0.0
*
* QItemModelScatterDataMapping is used to map roles of QAbstractItemModel to the XYZ-values
* of Q3DScatter points.
*
* QItemModelScatterDataMapping ignores rows and columns of the QAbstractItemModel and treats
* all items equally. It requires the model to provide at least three roles for the data items
* that can be mapped to X, Y, and Z-values for the scatter points.
*
* For example, assume that you have a custom QAbstractItemModel for storing various measurements
* done on material samples, providing data for roles such as "density", "hardness" and
* "conductivity". You could visualize these properties on a scatter chart:
*
* \snippet doc_src_qtdatavisualization.cpp 4
*
* \sa QItemModelScatterDataProxy
