Are the visual features in table 1.23 recommended over the ones in table 1.22?

What is the difference between data transformations (after the initial transformation from raw data) and database queries?

Most of the activities in figure 1.23 seem geared towards the individual. How would workgroups effectively participate in the process?

The paper suggests that many civilization advances have been facilitated by the invention of visual artifacts. Have any such advances been facilitated by information visualization, and if not, what kind of advances would you expect it to facilitate?

The first example of information visualization is the periodic table with dynamic queries. This example combines abstract and physical data. If this is example an example information visualization, where do you draw the line between scientific and information visualization?
