Art in Information Visualization

It was a delight reading about "Cyclogram" - a narrative of Salyut 6 space flight by russian cosmonaut, in chapter 5 of Tufte's book.
It is a masterpiece in visualization. So much information- multi dimensional information, all packed so nicely and presented on a piece of paper where one can choose to get the "bigger" picture at a glance or navigate through the details. Complete view, layers of informations, all connected through various dimensions of time and events, again in a mere 2-D paper!! Almost in the same spirit as Hans Rosling did with animated (3D) statistics in the TED video we saw in the class, or perhaps what Google is doing with Google stories.
