Stephen Few Blog Post on Multivariate Visualization

Categories: General Dave Rathbun @ 9:23 am

Really good read, in my opinion. Here’s the opening paragraph:

Almost all data visualizations are multivariate (i.e., they display more than one variable), but there are practical limits to the number of variables that a single graph can display. These limits vary depending on the approach that’s used. Three graphical approaches are currently available for displaying multiple variables:

  • Encode each variable using a different visual attribute
  • Encode every variable using the same visual attribute
  • Increase the number of variables using small multiples

In this article, we’ll consider each.
