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

In this paper the author has described how should one go about while planning for making a graphical interface design or visualization. The author insist on following few steps like first you should carry out the overview, then zoom and filter and later on focus on the details-on-demand. What he is trying to say here is that people/designers should gain an overview of all entire data available in the collection, the remove the data that you feel is not really interesting or unimportant and select an item and get details when needed. The he describes the different types of data that is available now a days like 1-dimensional, 2-dimensional, 3-dimensional, multidimensional , temporal, tree, network etc.

The author is absolutely right in saying that visualizing data definitely gives the user a better understanding of the information. The user finds it relatively easier to deal with an image or a graphical representation than scrolling through large sheets of data. He explains this by giving an example of the world map. If the user knows in which country a particular city is located then it becomes very easy for him to locate it on the map rather than scrolling through the sheet of data alphabetically. The design can always be made better by taking the advantage of the human perceptual abilities.
