Animate the adding of new values

On a line graph, it could be nice to have the impression that the values are added continuously even if it's not really the case. This would be made possible if the values where sliding continuously from the right to the left, and the last value is displayed after the duration of the slide.

This means that the graph will not be real time anymore, but the visualisation could be smoother and nicer to look. Any thoughts on this?
