1. A computer-implemented method for computer visualization of drugs for drug interaction information retrieval, comprising: acquiring, for each of multiple different substances, imagery of at least one external characteristic of a physical body of the substance; determining an identity of each of the multiple different substances based upon the at least one external characteristic from the acquired imagery; retrieving drug interaction data for each of the multiple different substances using the determined identities; correlating, using a processor, drug interaction data for at least one of the multiple different substances with at least one other of the multiple different substances; and displaying the correlated drug interaction data.
