Why Use Visualization?

There are 3 main categories of visualization:
  1. 1.
    Explanatory Visualization
  2. 2.
    Exploratory Visualization
  3. 3.
    Confirmatory Visualization

Explanatory Visualization

The aim of such a visualization is to explain something to somebody i.e. to get a message across.

Exploratory Visualization

The aim of such a visualization is to be able to extract information from data, without knowing exactly what that data is about. This allows a user to answer questions and generate new hypotheses.

Confirmatory Visualization

The aim of such a visualization is to verify an existing hypothesis.
Therefore, information visualization can be used for:
  • Communication: Explanatory Visualization
  • Analysis: Exploratory and Confirmatory Visualization
