Description

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?

Research direction
The issue suggests animating new values sliding from right to left in a line graph. Review the current rendering code for line graphs in Rickshaw, likely in files like 'src/rickshaw/graph/line.js' or similar. Look for how data points are added and rendered. The animation could be implemented by shifting the x coordinates of existing points and smoothly transitioning new points from the right edge. Check any existing animation utilities in the codebase. The maintainers may have opinions on performance vs. aesthetics, as noted in the existing comments.
