About

This page uses a dynamic three-dimensional scene to visualize the effect of two explanatory variables.

Data format:

  • The first row contains the graph title.
  • Column labels are on the second row, followed by between 20 and 100 observations.
  • Each data point has a label, followed by values for y, x1, and x2.
  • Commas separate the values, and each row ends with a semicolon.
  • This is the static data set used on this page:
