The tool Rosling is using is great for this specific task, but there are some perceptual issues that it doesn't address. Animation can be useful if you can interact with the presentation, stop, rewind, etc. Also, in the data presented by Rosling there is a general, strong trend and some minor ones. This is the limit, from perceptual point of view. If you have several trends you can't visually track all of them.
