Fig. 1. A data story about natural disasters represented in form of a storyline that was authored by a professional data analyst. The data facts in black (a, c, e, f) were created by the analyst as keyframes of the story, while the facts in red (b, d) were generated based on our interpolation algorithm. The algorithm searches through the fact space to find data facts that best fill the content gap between two keyframes. The story first illustrates an overall situation of global natural disasters (a-c) and gradually focuses on the situation in China (d,e). Finally, it reveals that floods have the most pernicious impact on China (f). The corresponding interpolation process is also shown under the data story. The searching path is marked in red and the nodes with yellow borders are the final selected interpolation results.
