  ///
  /// [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.
