Agenda
Anscombe’s Quartet was constructed by statistician Francis Anscombe in 1973
How do I interpret this data?
Statistical Properties:• Mean• Variance• Correlation• Linear Regression
* Anscombe, F. J. (1973). "Graphs in Statistical Analysis". American Statistician
The same across all four datasets!

Value of Data Visualizations
• Graphs should be telling a story that people understand
• Choose the best way to convey the message of the story

• Wordle.net was created by Jonathon Feinberg, which he now owns and operates for non-commercial purposes
• “a toy for generating ‘word clouds’ from text that you provide.”
Value of Data Visualizations
RAVE Visualization created using Cognos
Overview of RAVE
What is RAVE?
• RAVE stands for Rapidly Adaptive Visualization Engine, which is an IBM technology that drives data visualizations using a JavaScript grammar based language called JSON
• JavaScript Object Notation• Simpler than XML• Better suited to data-interchange• Lightweight, less grammar
What is JSON?
Overview of RAVE
• The Visualization object became available with Cognos version 10.2 • New chart types• Updates to existing chart types• Improved animation and interactivity• Visualization customizer application• Charts can be added into solution without waiting for Cognos release
How do I use Visualizations?
• From a user’s perspective, RAVE Visualizations are seamlessly integrated into Cognos Reports (show comparisons)
From a developer’s perspective, using a Visualizations is simply picking another tool in the toolbox
How do I use Visualizations?

How do I use Visualizations?
Functionality is similar to standard chart object
How do I use Visualizations?
Demo: Look at Visualization object in Report Studio
How do I install Visualizations?
Download new visualizations from AnalyticsZone.com
• New Library tab in the Admin panel (Cognos 10.2)
How do I install Visualizations?
• New “Library Administrators” role
How do I install Visualizations?
From Library tab, click “Import Visualizations…” and browse for the file
How do I install Visualizations?
Now the new Visualization is available for the developer.
