The hypothesis in visualization
Josh On, They Rule
All visualization begins with a hypothesis. As previously determined, visualization is an expressive medium, and as such aims to communicate abstract ideas through the use of data. Any successful visualization, therefore, allows drawing conclusions about the underlying data. These conclusions, while often revealing or surprising even for the author of the piece, are nonetheless driven by a particular hypothesis—a hypothesis as general as simply selecting a type or range of data for its perceived interest- or insight-generating qualities, or as specific as setting out to prove a certain claim based on the characteristics of the data source.
