how to draw a tree to see the hierarchy like "middle image"?

Hello there,

Thanks for the question. The image was drawn using custom code using the VMD package. There is no code to do this for you included with the library since, so you'd need to write something yourself. While it would potentially be a useful feature, it would be hard to generalise since the code works in arbitrary dimension.

Hope this helps.
