Lack of Integration with other Visualization Techniques

Ahlberg and Wistrand [5] have pointed out that successful visualization environments do not depend on one single powerful visualization, but rather on an assortment of visualizations appropriate for various tasks and data types. The use of different visualization techniques allows for representation of data from different points of view. Some of these views, depending on data characteristics or structure will provide a better understanding of the data than others. One such option of great promise, iconographic visualization, but currently it is not well integrated with other visualization techniques. The integration of the iconographic technique with other visualizations could be a key point in the use of this technique in exploring multidimensional data sets trying to discover hidden relations.

Grinstein et. al. [18] has pointed out the benefits of integrating the iconographic technique with systems for knowledge discovery. Up to now however no system has been developed providing such facilities. The idea of that integration is to use the iconographic visualization as a medium to identify visual clues that could be used as starting points for further exploration by, for example, a knowledge discovery system. The use of the iconographic technique in identifying possible points for further exploration has not been exploited to its full potential. Other visualization or analysis techniques could take advantage of the iconographic technique's capacity for creating global visual representations of data sets. Its capacity of producing displays that stimulate spontaneous perceptions of data structures, particularly of coherent data, could also be used for helping users in the process of identifying regions for further exploration. Its application to non-coherent databases is also promising, but more problematic as discussed next. The integration of the iconographic technique with analysis tools or other visualizations techniques might provide mechanisms for dealing with some of the problems faced with the application to non-coherent databases.
