Business Intelligence
Data Visualization
From Wikipedia
“Data visualization is the study of the visual representation of data, defined as information which has been abstracted in some schematic form, including attributes or variables for the units of information.”
Dashboards
From Wikipedia
“An Executive Information System (EIS) is a type of management information system intended to facilitate and support the information and decision-making needs of senior executives by providing easy access to both internal and external information relevant to meeting the strategic goals of the organization.”
Business Intelligence
• Visualizations take rich data (often KPI’s) and make it consumable
• Dashboards display one or more visualizations to help users make decisions
DEMO Slick Dashboards
Performance is …
The #1 Feature Request
Performance Recommendations
Use Category Series instead of Scatter Line Series Don’t Implement INotifyPropertyChanged on Bulk Data
updates Raise the Reset Event if you have a lot of changes Hide / Fix the Extent of Axis Labels Use Close to Real-World Data when Testing Performance If all else fails, post a sample to the forums
DEMO Performance
Making it Stick
Active Vision
• Graphics are cognitive tools that extend what our brain remembers
• Irrelevant information is removed from our brains and replaced with new information every second
Selective
Visual Attention • Focusing the user effectively on
the data you want them to see avoids competition
• Use signal techniques such as color, shape, tilt, arrow, angle, fade in, blink, blur, bold, size, etc
Common Design Mistakes
• Exceeding Screen • Inadequate Data Context • Excessive Detail • Deficient Measures • Inappropriate Display • Meaningless Variety • Inaccurate Encoding • Poor Data Arrangement • Ineffective Highlighting • Cluttering Display • Overuse Color • Unattractive Visual Display
Motion Framework
HTML5 / Silverlight, Windows
Phone 7 & WPF
Animate the story of your data
over time
Deeper end user analysis of
multiple data sets
• World Stats
• World Map
DEMO Motion Framework
Dashboard Success Strategies
Pick the Right Visualizations (use a UCD Process) Create meaningful visuals with concise messaging (Tell
the Truth) Focus the user on a single set or related set of data
(Show them what’s Important) Do not create competition between visuals (Keep it
Simple, think of Colors, Hues, Printing) Maximize the data ink on a chart (Get to the Point)
Wrap Up
Review
• Careful consideration for each dashboard visualization
• Consider what’s important to the user • Think about Active Vision of the consumer
of the dashboard • Understand the ramifications of Selective
Visual Attention • Ensure High Performance in Data • Use Tools like Motion Framework
