Abstract in different language:	We investigate the use of data-GIFs, i.e., graphics interchange format files containing short animations, to engage visualization viewers in learning about data visualization design pitfalls. A large number of data visualizations— among which, also several with bad data designs—are generated every day to convey information to lay audiences. To support non-expert viewers in recognizing common visualization design mistakes, we propose data-GIFs. Data GIFs are short educational animations played in automatic repetition with a single core message on how the design flaws of a given visualization can be identified. After defining what bad data visualization design entails, we inform the design requirements for the data-GIFs. We, subsequently, design four variants: two data-GIFs, which use respectively interchangeability and smooth transitions, a static variant with juxtaposition, and a data-video approach with audio. In a controlled user study with 48 participants, we compare the four variants. We demonstrate that interchangeability and smooth transitions effectively support viewers in assessing why elements characterizing bad data visualizations are indeed bad. Yet, smooth transitions are more engaging, and data-videos are more efficient for the identification of differences between bad and good data visualization designs
