Reaction: The Eyes Have It: A Task by Data Type Taxonomy for Information Visualizations.

In this paper, the authors have cited the large availability of information. This causes difficulty in exploring and understanding the data which leads to the need to generate a methodology or schema to represent the information. They talk about using color displays to depict the information in more effective manner.
The author identifies the seven basic tasks of abstraction which are overview, zoom, filter, details- on – demand, relate, history and extract. These discussions are further made on the basis of seven data types which are 1-D, 2-D, 3-D, multidimensional, temporal, multidimensional, tree and network. The author describes the basic operations or tasks as the mantra in visualizing the information. The author has also included a detailed description on advanced filtering. The paper very well supports the statement that the information can be well comprehended in visual form as compared to a text format. The paper does provide a promising hope to the field of information visualization and exploration.
