Several visualization task taxonomies have been defined in the literature, taking into account several factors, such as the user's goals when analyzing a visual representation of data, the data characteristics, how they are mapped onto the visualization, to name a few. Some studies also use task taxonomies as a tool to evaluate the effectiveness of visual representations. Because each task taxonomy may have been created for a different purpose, we find that they often overlap, and the task definitions are often implicit or ambiguous. We have analyzed several visualization taxonomies, and realized they crosscut different stages of the visualization process. In this work, we focus on the data transformations stage and define a set of datafunctions related to the tasks in the studied taxonomies. We specify these functions to bring clarity and consistency, as well as to enable them to be used in different scenarios. This work is a first step toward a more comprehensive visualization ontology.
