1"""Visualization tools for event camera data. 

2 

3This package contains various visualization tools for event streams, 

4including 3D plots, Open3D point clouds, and video reconstruction.

6Submodules are imported lazily (via ``__getattr__``, mirroring 

7:mod:`evutils`) so ``import evutils.vis`` does not eagerly pull in the heavy 

8``cv2`` / ``matplotlib`` / ``open3d`` / ``torch`` stacks. Access 

9``evutils.vis.plot3d`` / ``evutils.vis.reconstructor`` / ``evutils.vis.open3d`` 

10to resolve them on first use.
