Data Space
  • Multi-dimensional databases,
  • 1D timelines,
  • 2D maps,
  • 3D volumes,
  • Hierarchies/Trees directories,

Multi-dimensional
  • Fewer dimensions -gt easier
  • 1,2,3-D scatterplots
  • Clevelands rules
  • We will return to some more interesting 1,2,3-D
    cases later
  • What about many dimensional data? n-D
