Visualization as metaphor
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. [Note: In writing this it appears I misinterpreted their statement: see comments below.]
