However, it is not clear METHODOLOGY any discernible influence of animation what kind of animated transitions are either in accuracy nor in timing; both Two experiments were conducted to test YEAR possible between maps and charts and static and animated tasks had equally the effects of designed transitions.

In animated tasks, 2020 first experiment set an object tracking Therefore, the main objective of this it showed the benefits of staging over test revealing transition effects on the research is to determine how animated tweening.

Results highlighted a better animated transitions, statistical data, shape, size, and position. It compared performance of smooth staged graphics, maps, charts, cartography three different animated transitions animation for transitions with DESIGN OF TRANSITIONS among each other.

They are scatter plot effects on understanding of statistical (chart), bar chart, pie chart, proportional data. This experiment narrowed down to Identification of objects with the symbol map, flow map, and choropleth identification of map trends and objects highest/lowest value displayed a greater map. Each represents quantitative with the highest/lowest value. It number of correct answers in animated statistical data at discrete enumeration includes tasks with animated and static tasks than static ones (Fig. 4). Among units. graphics. The evaluation of results is transitions, smooth staged animation based on answers’ accuracy, time spent performed worse in accuracy than sharp Nine basic pairs of transitions between on completing each task, and subjective staged and tweened ones.

CONCLUSION Participants tended to be more successful in completing the tasks All in all, the experiments showed that starting from charts than from maps.
