-\section1 Visualizing Data
-
-Qt provides ready-made C++ classes and QML types for visualizing data in the
-form of charts and graphs, which are known to be best ways of analyzing data.
-\l{Qt Charts} and \l{Qt Data Visualization} are the two Qt add-ons that make
-data visualization using 2D and 3D models a reality.
-
-\section1 Displaying Web Content
-
-Qt provides the Chromium-based
-\l{Qt WebEngine}{WebEngine} layout engine, which enables you to embed web content
-into the Qt application. The engine can be integrated into both Qt Widget-based
-and Qt Quick-based applications.
-
-For more information about support for web content in Qt, see
