Wehrend's matrix

Available visualization techniques from different application disciplines are classified by data type (dimension 1) and intended visualization task (dimension 2) and entered into a matrix. This creates a catalog of visualization techniques. These techniques can be shared by scientists who do not know anything about the work of each other. "When visualization techniques are placed in the matrix formed by the objects [data types] and operations, Mackinlay's expressiveness and effectiveness criteria are implicitly dealt with." [WEH90]

"To find a visualization, the user must partition the problem into subproblems, until for each subproblem it is possible to find an entry in the matrix. A representation for the original complex problem can then be found by combining the candidate representation methods for the subproblems." [WEH90]

The 2D matrix is indexed by two dimensions:

objects are "the nature of the things" such as :

operations are the tasks the user wants to perform on the objects, such as:
