Effective graphical displays

A graph is a visual display of data to achieve an understanding of the underlying patterns and interrelationships of the data. Such visual representations of data often form the basis for inferences and decisions. However, a poorly chosen graphical form can lead to erroneous inferences. In this paper previously published graphs depicting biopharmaceutical, drug metabolism, formulation, and pharmacokinetic data are recast using alternate display methods in an attempt to better clarify the data structure. The display methods used include dot plots and trellis plots.
