There are a number of different task taxonomies in InfoVis at different levels of granularity.
Task Taxonomy of Relational Information Displays
by: [Zhang, 1996] based on [Carswell and Wickens, 1988]
There are three major types of display tasks:
- information retrieval
- comparison
- information integration
High-level tasks / purposes / goals of Visualization

On the interplay between task and representation
Thus, although there are no best displays that are efficient for all types of tasks, there is a correct or incorrect mapping between the representation of a display and the structure of a task.
[Zhang, 1996]
When a RID [Relational Information Display] has necessary and sufficient information for a task, the mapping between the display and the task is perfect. For example, length is a good representation for ratio comparison tasks because length is on a ratio scale and ratio comparison tasks require ratio scales.
