description
End users don't really care about data. They want information from data that helps them answer questions, make decisions and take actions. A good way of turning data into information is through visualization - a picture after all says more than a 1000 words. This presentation shows some striking examples of that statement – both in the real world as well as in the world of IT. Some keywords: info graphics, dashboards, charts, traffic lights, maps, icons, emoticons. The story will convince you to look beyond traditional ways of presenting data – in order to make the user experience more intuitive, productive and with less opportunity for misinterpretation. Leverage the power of the IT systems to pre-process, pre-interpret and present information extracted from data in a meaningful way, poised for action.

Visualization
• Starting from Data
• Create a Presentation
• Of Relevant, Correct, Complete, Timely Information
• That allows
– Interpretation => Understanding
=> Insight => Wisdom/Vision
– Re-action
– Pro-action
• To ensure the User carries out his or her Responsibilities

Visualization Design
• What are the User’s responsibilities?
• What actions/decisions may have to be taken?
• What information is required to perform an action?
• Which information determines if an action should be taken?
• How should the user be informed about an action that needs taking?
– What shape does the call-to-action take?
• How should be the information required to start an action or make decision be presented?
• What data is the information derived from [and how]?

Power of Graphical Visualization
• Activates our Associative Brain
– Connections
– Memories
– Unconscious/background processing
• Multi-dimensional
– Color
– Size
– Shapes/ Font
– Story/Atmosphere
– Icons
– Sound
– Animation
– 3D presentation
– Interact (drill down, roll up, pivot)

A biology lesson
• […] our visual system is extremely well built for visual analysis. There's a huge amount of data coming into your brain through your eyes; the optic nerve is a very big pipe, and it sends data to your brain very quickly (one study estimates the transmission speed of the optic nerve at around 9Mb/sec). Once that data arrives at the brain it's rapidly processed by sophisticated software that's extremely good at tasks such as edge detection, shape recognition, and pattern matching.
• […] pattern matching, is the key when it comes to discussing the benefits of presenting information visually. Typically, the important messages in data are represented in the patterns and pattern violations: trends, gaps, and outliers. This is the interesting stuff. This is meaning. This is what we go to the data hoping to find.
• Visualizations are so capable and powerful at conveying knowledge that they can be more effective than words at changing people's minds. ( "Graphical corrections are also found to successfully reduce incorrect beliefs among potentially resistant subjects and to perform better than an equivalent textual correction.")
