Traditionally, however, it was regarded as only a tool, with information content and visualization analogous to an object and its representation, respectively. These days, visualization is increasingly seen as an integral part of information con tent, without which data collections may lose significant value. This paper is devoted to applying a new visualiza tion scheme – SequenceWorld – to a genetics database. We view a collection of EST sequences as a browsable virtual world. Sequences cluster according to their ho mologies. Their relative position, color and shape codings offer direct visual perception of a significant amount of information, which would otherwise be available only via extensive analysis of numerical and textual data. We dis cuss the usability of SequenceWorld for completing tradi tional and novel genetic database search tasks, particu larly since a holistic view of a complete genome has recently become possible.
