Computational study demonstrates semiautomated Box-Cox power transformations improve visual parameters across graphical displays, highlighting methods for clearer data visualization.

Key Points

To investigate the application of the Box-Cox family of power transformations for semiautomatically adjusting visual parameters and improving the interpretability of graphical representations.
Applied Box-Cox power transformations to precondition skewed data distributions toward symmetry.
Tested automated visual parameter adjustments across time-series scaling, axis transformations, and color binning for choropleth maps.
Power transformations effectively normalized skewed data distributions to facilitate clearer visual perception of underlying variations.
Semiautomated parameter adjustments improved display contrast in choropleth color scales and compressed extreme values in time-series plots, though requiring careful handling of automated edge cases.
