/**
 * Returns a nice domain for the given scale type and domain.
 * Does not modify the original domain.
 *
 * Providing a count improves the nice domain calculation by trying to align tick values to round
 * numbers or dates.
 *
 * For example, if you have a domain of [29, 72] and there are 5 ticks, the nice domain will be
 * [20, 80] so that the ticks can be at [20, 35, 50, 65, 80].
 * However, if there are 11 ticks, the nice domain will be [25, 75] so that the ticks can be at
 * [25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75].
 *
 * @param scaleType The type of the scale (e.g., 'linear', 'log', 'time', etc.).
 * @param domain The domain to be made nicer.
 * @param count An optional number of ticks to improve the nice domain calculation. Defaults to 5.
