  relationships between every two variables
• you dont have to know what youre looking for
• Heres what Im interested in, theres where it
  is

Agent-Based Modeling

• Details on demand
• Juxtaposes different variables for comparison in
  one glance
• Allows for multiple resolutions
• A framework for combining different models
• Would work great in a collaborative environment
  such as a multi-touch table

Agent-Based Modeling

• Visualization is not an after thought
• Embed analysis and reasoning directly into the
  visualization

19
Interactive PCA

• Principal Component Analysis (PCA)
• Based on identifying Eigenvectors and Eigen
  values
• Most commonly used in finding clusters
