The problem is not that LineSet doesnt support zoom parameter but that o3d.visualization.draw_geometries doesnt support zoom parameter when passed without front, lookat, and up params. More information here - https://stackoverflow.com/a/76828436/1874627 answered by me.

The code here docs/jupyter/visualization/visualization.ipynb however will work if run directly from open3d repository, since open3d jupyter notebook used a hack to override o3d.visualization.draw_geometries. See here:- https://github.com/isl-org/Open3D/blob/master/docs/jupyter/open3d_tutorial.py#L67

As a quick fix, I will still go for accepting this PR, as above stackoverflow question clearly shows users are copying code with zoom parameter.

Alternative option - Remove https://github.com/isl-org/Open3D/blob/master/docs/jupyter/open3d_tutorial.py#L67 and use import correctly, i.e. open3d_tut.jupyter_draw_geometries. This shows a custom method is called that creates Open3D window as well as captures a screenshot of the window before closing.

IMO - draw_geometries method should be extended to include the functionality provided by https://github.com/isl-org/Open3D/blob/master/docs/jupyter/open3d_tutorial.py#L17C1-L62C25
