### My Question

I am using VSCode to ssh into a remote server, so I can only get visualizations to work with the `draw_plotly` method. However it seems very poorly documented. I want to visualize multiple `o3d.geometry.PointCloud()`s on the same window, lying side by side. If I pass in multiple point clouds directly into `draw_plotly` it will overlay them, which is not the desired behavior. Does Open3D currently support this feature?
