-According to Edward Tufte in his book, The Visual Display Of Quantitative Information
- Excellence in statistical graphics consists of complex ideas communicated with clarity, precision, and efficiency. Graphical displays should
- show the data
- induce the viewer to think about the substance rather than about methodology, graphic design, the technology of graphic production or something else
- avoid distorting what the data have to say
- present many numbers in a small space
- make large data sets coherent
- encourage the eye to compare different pieces of data
- reveal the data at several levels of detail from a broad overview to the fine structure
- serve a reasonably clear purpose: description, exploration, tabulation or decoration
- be closely integrated with the statistical and verbal descriptions of a data set.
Graphics reveal data.
