70 * Direction of the custom motion.dev intro reveal. Recharts' own area animation
71 * is permanently disabled (it drew the line after the dots had already popped
72 * in) — these reveals replace it.
73 *
74 * NOTE: a reveal is a per-frame animated SVG mask, so it is heavier than a
75 * static chart. `"none"` opts out entirely; it is also what a device with the
76 * OS "reduce motion" preference falls back to automatically.
