What is Data Visualization?
"Data visualization is the presentation of data in a pictorial or graphical format. It enables decision makers to see analytics presented visually, so they can grasp difficult concepts or identify new patterns. With interactive visualization, you can take the concept a step further by using technology to drill down into charts and graphs for more detail, interactively changing what data you see and how it’s processed." - SAS
Visualization from NASA's Jet Propulsion Lab missions past, present, future, and proposed.
