-    \title Scatter Example
-    \ingroup qtdatavisualization_examples
-    \brief Using Q3DScatter in a widget application.
-
-    The scatter example shows how to make a simple 3D scatter graph using Q3DScatter and
-    combining the use of widgets for adjusting several adjustable qualities. The example shows
-    how to:
-
-    \list
-        \li Create an application with Q3DScatter and some widgets
-        \li Use QScatterDataProxy to set data to the graph
-        \li Adjust some graph properties using widget controls
-    \endlist
-
-    For instructions about how to interact with the graph, see \l{Qt Data Visualization Interacting with Data}{this page}.
-
-    \image scatter-example.png
-
-    \include examples-run.qdocinc
-
-    \section1 Creating the Application
-
-    First, in main.cpp, we create a QApplication, instantiate Q3DScatter, and a window container
-    for it:
-
-    \snippet scatter/main.cpp 0
-
-    The call to QWidget::createWindowContainer is required, as all data visualization graph classes
-    (Q3DBars, Q3DScatter, and Q3DSurface) inherit QWindow. Any class inheriting QWindow cannot be used
-    as a widget any other way.
-
-    Then we'll create horizontal and vertical layouts. We'll add the graph and the vertical
-    layout into the horizontal one:
-
-    \snippet scatter/main.cpp 1
-
-    We're not using the vertical layout for anything yet, but we'll get back to it in
-    \l {Using widgets to control the graph}
-
-    Next, let's create another class to handle the data addition and other interaction with the
-    graph. Let's call it \c ScatterDataModifier (See \l {Setting up the graph} and
-    \l {Adding data to the graph} for details):
-
-    \snippet scatter/main.cpp 2
-
-    The application main is done. We can show the graph and start the event loop:
-
-    \snippet scatter/main.cpp 3
-
-    \section1 Setting up the Graph
-
-    Let's set up some visual qualities for the graph in the constructor of the \c ScatterDataModifier
-    class we instantiated in the application main:
-
-    \snippet scatter/scatterdatamodifier.cpp 0
-
-    None of these are required, but are used to override graph defaults. You can try how it looks
-    with the preset defaults by commenting the block above out.
-
-    Finally we create a QScatterDataProxy and the associated QScatter3DSeries. We set custom label format
-    and mesh smoothing for the series and add it to the graph:
-
-    \snippet scatter/scatterdatamodifier.cpp 2
-
-    That concludes setting up the graph.
-
-    \section1 Adding Data to the Graph
-
-    The last thing we do in the \c ScatterDataModifier constructor is to add data to the graph:
-
-    \snippet scatter/scatterdatamodifier.cpp 3
-
-    The actual data addition is done in \c addData() method. First we configure the axes:
-
-    \snippet scatter/scatterdatamodifier.cpp 4
-
-    This could have been done in the constructor of \c {ScatterDataModifier}, but we added it here
-    to keep the constructor simpler and the axes configuration near the data.
-
-    Next we create a data array:
-
-    \snippet scatter/scatterdatamodifier.cpp 5
-
-    and populate it:
-
-    \snippet scatter/scatterdatamodifier.cpp 6
-
-    Finally we tell the proxy to start using the data we gave it:
-
-    \snippet scatter/scatterdatamodifier.cpp 7
-
-    Now our graph has the data and is ready to be used. There isn't much interaction yet, though,
-    so let's continue by adding some widgets to play with.
-
-    \section1 Using Widgets to Control the Graph
-
-    First, back in the application main, we'll create some widgets:
-
-    \snippet scatter/main.cpp 4
-
-    And add them to the vertical layout we created earlier:
-
-    \snippet scatter/main.cpp 5
-
-    Now, let's connect them to methods in ScatterDataModifier:
-
-    \snippet scatter/main.cpp 6
-
-    Here are the methods in ScatterDataModifier the signals were connected to:
-
-    \snippet scatter/scatterdatamodifier.cpp 8
-
-    And so we have an application in which we can control:
-
-    \list
-        \li Label style
-        \li Camera preset
-        \li Background visibility
-        \li Grid visibility
-        \li Dot shading smoothness
-        \li Dot style
-        \li Theme
-        \li Shadow quality
-        \li Label font
-    \endlist
-
-    \section1 Example Contents
