Final answer:
Animating data, particularly in line graphs or bubble charts like those seen in Hans Rosling's presentations, provides a moving picture of change over time, helping to better understand trends, patterns, and relationships in data such as human population shifts and economic growth.
Step-by-step explanation:
Animating data over time, such as using a line graph to track changes, offers a dynamic visual representation of trends and patterns that static data cannot. For instance, when discussing human population changes or economic growth across the world, the ability to see these changes as they develop over time can provide clear insights into the speed and scale of changes as well as correlations between different variables, like income and health.
One renowned example is the presentations by Hans Rosling, where he used animated bubble charts to showcase changes in world development indicators, which allowed viewers to understand complex data in a straightforward, often enlightening way. Such visualizations help to illustrate and understand relationships and trends in the data, identifying patterns such as the decrease in unemployment rates or an increase in average life expectancy related to economic improvements over time.
