“A visualization method is a systematic, rule-based, external, permanent, and graphic representation that depicts information in a way that is conducive to acquiring insights, developing an elaborate understanding, or communicating experiences (Lengler & Eppler, 2007, p1)

Principles of Graphical Excellence
“Graphical excellence is that which gives to the viewer the greatest number of ideas in the shortest time with the least ink in the smallest space” (Tufte, 1983, p51)

Dr. John Snow's map of deaths from a cholera outbreak in relation to the locations of public water pumps
Tufte (1983, p. 24) says, "Snow observed that cholera occurred almost entirely among those who lived near (and drank from) the Broad Street water pump. He had the handle of the contaminated pump removed, ending the neighborhood epidemic which had taken more than 500 lives."

Like good writing, good graphical displays of data communicate ideas with clarity, precision, and efficiency.
Like poor writing, bad graphical displays distort or obscure the data, make it harder to understand or compare, or otherwise thwart the communicative effect which the graph should convey.

Conclusion
“Design is choice … what is to be sought in designs for the display of information is the clear portrayal of complexity. Not the complication of the simple; rather the task of the designer is to give visual access to the subtle and the difficult-that is, the revelation of the complex.”
