3/// Animates the values of a chart's series.
4///
5/// The animator keeps the values the chart showed last and the values it
6/// should show now, and interpolates between them. The chart's layout
7/// is recomputed on every frame of the animation, so the shapes really
8/// move rather than jumping at the end.
9///
10/// The clock and the easing come from `euv-engine`: the chart's motion
11/// is the framework's motion, down to the delay and the pause. The
12/// engine's tween counts in seconds and the chart's API counts in
13/// milliseconds, and the conversion happens here and nowhere else.
