Tables of numbers attain maximum densities of only 300 characters per square inch or 50 characters per square centimeter. In contrast, graphical displays have far greater resolutions; a cartographer notes “the resolving power of the eye enables it to differentiate to 0.1 mm where provoked to do so.” Distinctions at 0.1 mm mean 250 per linear inch, which implies 60,000 per square inch or 10,000 per square centimeter, which is plenty.
