1
Many Eyes

• Visualizing the Arctic for the International
  Polar Year

2
What is Many Eyes?

• For shared visualization and discovery
• Easily converts data tables to interactive,
  colorful graphs or visualizations
• Research project of its own still a work in
  progress, updating and improving daily.

Who is Many Eyes?

• Small division of IBMs Collaborative User
  Experience research group
• Martin Wattenberg, Jesse Kriss, Fernanda Viégas,
  Frank van Ham, and Matt McKeon
• Fernanda Viégas is in touch with WITS

Polar Bears Basic Example

• Takes work to understand
• More useful if its in some graphical form

5
Polar Bears Basic Example

• Create a visualization
• Easier to understand
• Interactive

6
Sea Ice Extent Bubble Chart

• Sea Ice Extent the amount of ocean that is
  covered by sea ice.
• Ice is melting due to global warming.
• How is the sea ice extent changing?

7
Sea Ice Extent Treemap

• Multiple ways to visualize the same data
• Some ways are better than others
• A better way to use the Treemap

8
Creating a Data Set

• Need a Data Set to make a Visualization
• Start an Excel Spreadsheet
• View Visualization Types to figure out which
  graph (or graphs) will work with your data
• Read about the graph to figure out how the data
  must be entered
• Participate gt Upload data set

9
Creating a Data Set Line Graph

• Simple Example Peary Caribou
• Complex Example CO2 Emissions

10
From Data To Visualization

• Choose type
• Make sure data is compatible
• Select view
• Highlight areas
• Comment to explain the graph
