What is data visualization? A simple answer might be something like the graphic representation of data. But to get a better understanding of what practitioners of data visualization do, let’s start with the term data. By data, I mean raw, unorganized facts and numbers.
Practitioners of data visualization take raw, hard-to-grasp data and turn that data into information by providing context and a purpose.
