We are collecting samples of presentations that integrate Natural Language and Graphics in order to describe and analyze the components and the structure of such presentations. We focus on argumentative presentations (i.e. presentations that are making claims/points about the data). We want to determine how text and graphic contribute to the construction of arguments. This includes:

• Categorize points/claims made by means of presentations, trying to abstract away from the specific domain.
• Determine what kind of graphical or linguistic techniques and their combination support specific points. Among others:
• Role of redundancy between text and graphics (e.g. the text repeats/stresses facts already expressed by the graphics) and in the graphics itself (e.g. cyclical time-series, redundant mapping from data properties to graphical properties)
• How facts can be presented with different degrees of accuracy.
• When/Why some particular aggregations/disaggregations are shown?
• When/Why some particular subsets of the data are selected or highlighted?
• Different definitions for the same change.
