All visualization begins with a hypothesis, a hypothesis about the data that the choice of a particular formal expression aims to address. As previously determined, visualization is an expressive medium, and as such aims to communicate abstract ideas through the use of data. Any successful visualization, therefore, allows drawing conclusions about the underlying data. These conclusions, while often revealing or surprising even for the author of the piece, are nonetheless driven by a particular hypothesis—a hypothesis as general as simply selecting a topic or a particular type or range of data from within a certain context, with the anticipation of usefulness or insight, or as specific as setting out to prove or disprove a claim based on the characteristics of the data source.

Artistic data-based visualization
In his article “Visualization Criticism—The Missing Link between Information Visualization and Art”, Robert Kosara analyzes the gamut of data-based visualization between the two poles of pragmatic and artistic visualization. On pragmatic visualization techniques, he writes: “Pragmatic visualization techniques are also often general, and can be applied to many different data sets. This is considered a strength, because the user can gain experience with the method and apply that to different data, rather than having to start from scratch again.” The opposite is true for artistic visualization, which communicates a specific concern, using data as a proof that the concern is real. As opposed to pragmatic visualization, which aims for generalization, artistic visualization aims for specificity in the relationship between representation and subject matter.
Identity and the Branded Community 3 comments
Branded communities are an emerging phenomenon. Certainly, the term “branded community” is increasing in popularity. Yet—and this should not come as a surprise—brand has always been an important factor in regard to communities, and not only new communities. In this context, brand is a platform for creating and communicating a sense of place; it is the stated or perceived identity of a community. Branded communities, in their attempt to formalize sense of place, are not only the latest chapter in the ongoing narrative of the ideal or utopian city; they are also the outcome of a changing relationship between identity and community.
Visualization as metaphor 1 comment
In their paper Artistic Data Visualization: Beyond Visual Analytics, Fernanda B. Viégas and Martin Wattenberg claim that artistic data visualizations “…must be based on actual data, rather than the metaphors or surface appearance of visualization.” What they seem to be saying (though I will admit I may be reading too much into this statement) is that metaphor cannot apply to any ‘artistic’ visualization directly derived from data. While the article is well written and researched, I will try to explain why I fundamentally disagree with this premise (Martin informs me that I misinterpreted their statement, please see comments).
Metaphor and analogy in visualization
Curtis Wong of Microsoft’s Next Media Research group describes the architecture of information in three layers of what he calls a contextual pyramid: Engagement, context, and reference. Engagement draws the recipient in, context offers an explanation of the information source, and reference gives the ability to draw conclusions and connects to related resources. Metaphors and analogies are rhetorical devices which are used most often at the level of engagement, and can apply to concepts expressed through any form or medium.
