/// **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.
