+/// @brief \cpp_class{ kodi::addon::CInstanceVisualization }
+/// **Visualization add-on instance**\n
+/// [Music visualization](https://en.wikipedia.org/wiki/Music_visualization),
+/// or music visualisation, is a feature in Kodi that generates animated
+/// imagery based on a piece of music. The imagery is usually generated and
+/// rendered in real time synchronized to the music.
+///
+/// Visualization techniques range from simple ones (e.g., a simulation of an
+/// oscilloscope display) to elaborate ones, which often include a plurality
+/// of composited effects. The changes in the music's loudness and frequency
+/// spectrum are among the properties used as input to the visualization.
+///
+/// Include the header @ref Visualization.h "#include <kodi/addon-instance/Visualization.h>"
+/// to use this class.
+///
+/// This interface allows the creation of visualizations for Kodi, based upon
+/// **DirectX** or/and **OpenGL** rendering with `C++` code.
+///
+/// Additionally, there are several @ref cpp_kodi_addon_visualization_CB "other functions"
+/// available in which the child class can ask about the current hardware,
+/// including the device, display and several other parts.
+///
+/// ----------------------------------------------------------------------------
+///
+/// **Here's an example on addon.xml:**
+/// ~~~~~~~~~~~~~{.xml}
+/// <?xml version="1.0" encoding="UTF-8"?>
