ABSTRACT
This chapter discusses how one could design readable and clear data graphics. It focuses on design decisions that can affect the efficacy of data visualizations. There are some simple, core design standards applicable to every chart. There are 10 key design standards. They enable creation of readable and interpretable data graphics. Many of the standards are based on the work of leaders in the field of information visualization, including Edward Tufte, Dona Wong, and Stephen Few. The resolution and file types differ for printed publications, projected slide presentations, and web-based displays. Paper publications: for printed charts, determine how the chart will look in grayscale and in color. It should be readable in both. Consider the paper grade and finish. Save charts using high resolution for best printing quality. Web-based displays: for static data graphics presented on a web page, use a minimum resolution of 150 pixels per inch.
