This article focuses on the ontology level of visualizers, which describes concepts using a set of constructors with a preagreed meaning, for example, through a set of relationships that can be asserted between primitives. Visualizers have to think about how people extract meaning from pictures, what people understand from a picture, how pictures are imbued with meaning, and how in some cases that meaning arises within a social and/or cultural context. In the figure, visualization begins when someone has data that they wish to explore and interpret; the data are encoded as input to a visualization system, which may in its turn interact with other systems to produce a representation. This is communicated back to the users, who have to assess this against their goals and knowledge, possibly leading to further cycles of activity. Each phase of this process involves communication between two parties. |
