Thanks to continuously dropping storage costs and web access, users are becoming exposed to ever-increasing amounts of data, which is putting pressure on the traditional information retrieval model that is usually based on data retrieval by keyword search. The problem is that as the amount of searchable data soars, the retrieval process can become inefficient if the user's vocabulary does not match the index vocabulary used by the search process, or the user can not easily constrain a search path based on context (for an illustration of the importance of context, see this article). This paper makes the case that the context problem can be overcome through data visualization, which provides an additional dimension for the user to specify their desired context. It then provides a brief introduction to the fundamentals of data visualization, followed by examples of some leading visualization tools.
