Star Coordinates

1
Star Coordinates

• A Multi-dimensional Visualization Technique with
  Uniform Treatment of Dimensions

2
The Problem . . .

• Data typically viewed in 2D and 3D visualizations
• Mapping a given point to its corresponding data
  values becomes increasingly difficult
• Rotation provides assistance in 3D
• Star Coordinates is useful for dimensions greater
  than 3

3
Basic Idea

• Coordinate system based on axes positioned in a
  star, or circular pattern
• Users are willing to sacrifice some information
  during initial analysis
• By sacrificing detail, underlying patterns in the
  data are revealed

4
Using the system

• Scaling changes contribution to resulting
  visualization
• Rotation induces correlation between data columns
• Modification of queries using rotation and scaling

Drawbacks

• Detail description sometimes obscured by data
  points
• Learning curve for operation

7
Conclusion

• Particularly useful for identifying clustering
  of data based on user defined queries
• Provides users with an initial interpretation of
  data
