     \section1 Item models and data mapping
 
     For common use cases, Qt Data Visualization offers specialized proxies. One such case is having
     data in an item model (QAbstractItemModel subclass), which is a common way to store data in
-    Qt applications. Each of the visualization types offers a special proxy and a corresponding mapping
-    class for this purpose, for example, QItemModelBarDataProxy and QItemModelBarDataMapping for Q3DBars.

     These proxies are simple to use: just give them a pointer to the item model containing the
-    data and the mapping object containing rules how to map the data into format the basic proxy can
-    digest.

+    values for different roles. For example, with QItemModelBarDataProxy you can specify which
     role is used to determine which row the item belongs to, which role does the same for columns,
     and which role specifies the value of the item. When the proxy resolves the data from the model,
     it uses these mappings to generate the rows and columns of the bar graph.
