The code that drew it

A still frame holds a repeating animation at its first frame and a one-shot at its last, because a still of a moving thing is not reproducible. Run the gallery to review motion.

fn sparkline(_window: &mut Window, cx: &mut App) -> AnyElement {
    let theme = cx.theme().clone();
    let points = [
        SparklinePoint::new(0.0, 0.20),
