What is Data Visualization?
What is Data Visualization? How can it be explained through a visual diagram? Can data visualization be... visualized? David McCandless answered this recursive issue on his impressive blog Information is Beautiful already a while ago, with a 4-layered vendiagram graph that combines the concepts of "Interestingness", "Function", "Form" and "Integrity". More recently, FFunction attempted to simplify the depiction of data visualization further by proposing a classic 3-layered vendiagram that mash the areas: "Information" , "Design" and "Communication", with its many intermediate steps. It actually does not necessarily stop there: we proposed back in 2007 (PDF), the combination of "Aesthetics", "Data" and "Interaction". You can compare the three approaches below. Are there more models around?
