    Data are observations of some unknown phenomenon we like to gain more insight on. There are no limits in the number of attributes this phenomenon can have, and it may or may not have a spatial reference. The number of attributes that are being measured depends on the number of channels of the sensor that is used to acquire the data. In 3D imaging we usually have a single channel that measures the attenuation of some beam of energy. The spatial reconstruction of the measured phenomenon can then be accomplished by some form of inversion, either rooted in mathematics or in numerical optimization. I will discuss a few examples where we have made contributions to research â€" X-ray Tomography and Electron Tomography. These reconstruction products are then easily visualized with 3D rendering. On the other hand, data that do not have a spatial reference get reconstructed in information spaces. The difference here is that the locations in these information spaces do not need to be reconstructed via tomography â€" they are explicitly given. And so the challenge is not the spatial reconstruction â€" rather, it is the mental reconstruction of the phenomenal once the number of attributes goes above 3. I will show a few examples of the types of visual techniques we have devised to help in the comprehension of these high-dimensional phenomenal.
