  • 5. Big Data
  • 6. Big Data != Lots of DataTHE THREE VSVolume- OK, Big Data = Lots of Data (sometimes)- No objective size at which this is a problem
  • 7. Big Data != Lots of DataTHE THREE VSVelocity- Real-Time?- TPM (Tweets Per Minute)
  • 8. Big Data != Lots of DataTHE THREE VSVariety- Data coming in from a variety of sources- Internal, External- Different Formats
  • 9. Data VisualizationWhy should we be interested in visualization? Because the human visual system is a pattern seeker of enormous power and subtlety. The eye and the visual cortex of the brain form a massively parallel processor that provides the highest- bandwidth channel into human cognitive centers. At higher levels of processing, perception and cognition are closely interrelated, which is the reason why the words “understanding” and “seeing” are synonymous.- Colin Ware, 2000
  • 10. Visualization Defined"the use of interactive visual representations of abstract data to amplify cognition" - Colin Ware, 2004"the use of computer-supported, interactive, visual representations of abstract data to amplify cognition" -Ben Schneiderman , U of Maryland, 1999
  • 11. Big Data & Visualization – Use Caution“Unquestioning empiricists” - trust analysis over judgment“visceral decision makers” - go exclusively with their gut“Informed skeptics”—the employees best equipped to make good decisions—effectively balance judgment and analysis, possess strong analytic skills, and listen to others’ opinions but are willing to dissent. They’re the kind of data-savvy workers every company should try to cultivate. However, we found that only 38% of employees, and 50% of senior managers, fall into this group.- Shvetank Shah, Andrew Horne, and Jaime Capellá for Harvard Business Review
  • 12. Big Data VisualizationVolume: How do we visualize all this data?Schniedermans Mantra:"Overview First, Zoom & Filter, then Details-on-Demand“e.g. http://internet-map.net/
  • 13. Big Data VisualizationVelocity: How do we deliver changing data?Real-Time Visualizationhttp://tweetping.net/Dashboardshttp://chartbeat.com/demo/
  • 14. Big Data VisualizationVariety: How do we deal with all these dimensions?Multivariate Visualization- encode as much as possible: placement, size, color, shape, direction- use the right chart: some chart types (parallel coordinates) are naturally suited for multivariate visualization- dont forget small multiples - sometimes the best chart is more charts
