 * \class QItemModelBarDataMapping
 * \inmodule QtDataVisualization
 * \brief Data model mapping for Q3DBars.
 * \since 1.0.0
 *
 * QItemModelBarDataMapping is used to map roles of QAbstractItemModel to rows, columns, and values
 * of Q3DBars. There are three ways to use QItemModelBarDataMapping:
 *
 * 1) If useModelCategories property is set to true, QItemModelBarDataMapping will map rows and
 *    columns of QAbstractItemModel to rows and columns of Q3DBars, and uses the value returned for
 *    Qt::DisplayRole as bar value by default.
 *    The value role to be used can be redefined if Qt::DisplayRole is not suitable.
 *
 * 2) For models that do not have data already neatly sorted into rows and columns, such as
 *    QAbstractListModel based models, you can define a role from the model to map for each of row,
 *    column and value.
 *
 * 3) If you do not want to include all data contained in the model, or the autogenerated rows and
 *    columns are not ordered as you wish, you can specify which rows and columns should be included
 *    and in which order by defining an explicit list of categories for either or both of rows and
 *    columns.
 *
 *    For example, assume that you have a custom QAbstractItemModel for storing various monthly values
 *    related to a business.
 *    Each item in the model has roles "year", "month", "income", and "expenses".
 *    You could do the following to display the data in a bar chart:
