This seems like a straightforward question, but it’s proven to be a difficult one to answer. Even visualization researchers – people who think about the subject all day and every day – don’t have a clear definition of what visualization is. Is it synonymous with information graphics? Does visualization have to be computer generated? Does data have to be involved, or can it be abstract? The answers vary depending on who you ask.
