Data Visualization vs. Information Visualization
What are the differences between DataVis and InfoVis? Yijisoo
Hard question
Wohoo - that's the one million dollar question I was thinking about many times ;-)
I've found no definition in literature that would point out the differences between the two terms. Anyways, I tried to differentiate the two terms by means of needed semantics for meaningful visualizations:
Data Visualization: Visualization techniques for data represent a set of parameters over time graphically whereas no semantics are needed in order to create a meaningful visualization (e.g., Scatterplot). This also includes simple processing on raw data that do not require semantics (derived data; e.g., Histogram, Boxplot, mean, other statistical measures, clustering, etc.). Furthermore, data visualization techniques are often of static nature.
Information Visualization: In contrast to the previous class, visualization techniques for information need semantics, i.e., the meaning of different parameters and their interrelationships or structure are important in order to create a meaningful representation (e.g., InfoBUG glyph).
What do you think about this definitions?
