` Tufte (1983)
` Present many numbers in a small space - but also emphasize the important numbers.
` Make large data sets coherent, and encourage the audience to compare different pieces of data.
` Reveal the data at several levels of detail.
` Design for your audience • Different audiences may need different visualizations. • Focus on emphasizing the messages that you are trying to
convey to your audience. ` Accurately represent the data
• Show the underlying data without distortion ` Keep it clear
• All visual clutter kept to a minimum
