Questions and Answers

What is the purpose of a scatterplot matrix?

  • To display data values as features of icons
  • To show the data as a series of parallel coordinates
  • To visualize the relationships between multiple variables in a dataset (correct)
  • To represent the data as a perspective landscape

What is the key characteristic of parallel coordinates visualization?

  • It encodes information using shape and color of icons
  • It uses equidistant axes parallel to one of the screen axes (correct)
  • It displays data values as features of Chernoff faces
  • It represents data as a perspective landscape

Which of the following is an example of an icon-based visualization technique?

  • Scatterplot matrix
  • Parallel coordinates
  • Perspective landscape
  • Chernoff faces (correct)
