This image shows a 3D graph on a 2D screen, and it honestly looks extremely underwhelming. However, imagine this visualization in 3D, where you can walk around and view all of this information at the palm of your hand. Since humans are instinctively wired to understand spatial relationships, I think that a lot of things could really benefit being moved to the virtual world.
