## Abstract

Graphical presentations can be used to communicate information in relational data sets succinctly and effectively. However, novel graphical presentations

about numerous attributes and their relationships are often difficult to understand completely until explained. Automatically generated graphical presentations must therefore either be limited to simple, conventional ones, or risk incomprehensibility. One way of alleviating this problem is to design graphical presentation systems that can work in conjunction with a natural language generator to produce “explanatory captions.” This paper presents three strategies for generating explanatory captions to accompany information graphics based on: (1) a representation of the structure of the graphical

presentation (2) a framework for identifying the perceptual complexity of graphical elements, and (3) the structure of the data expressed in the graphic.

We describe an implemented system and illustrate how it is used to generate explanatory captions for a range of graphics from a data set about real estate

transactions in Pittsburgh.
