.. py:class:: ValidationVisualizer(backend: str = 'desktop', object_mode: str = 'z', object_cmap: str = 'plasma', background_mode: str = 'intensity', background_cmap: str = 'viridis', background: tuple[float, float, float] = (1, 1, 1), point_size: int = 3, port: int = 8888)

   Validation visualizer that highlights one classification label.

   The visualization uses distinct color mappings for the selected object label
   and the remaining background points.
