68 * Direction of the custom motion.dev intro reveal. Recharts' own line animation

70 * in) — these reveals replace it.
71 *
72 * NOTE: a reveal is a per-frame animated SVG mask, so it is heavier than a
73 * static chart. `"none"` opts out entirely; it is also what a device with the
74 * OS "reduce motion" preference falls back to automatically.
