 * Returns a new vertical waffle mark for the given *data* and *options*; the

 * should be ordinal. For example, for a vertical waffle chart of Olympic
 * athletes by sport:
 *
 * ```js
 * Plot.waffleY(olympians, Plot.groupX({y: "count"}, {x: "sport"}))
 * ```
 *
 * If neither **y1** nor **y2** nor **interval** is specified, an implicit
 * stackY transform is applied and **y** defaults to the identity function,
 * assuming that *data* = [*y₀*, *y₁*, *y₂*, …]. Otherwise if an **interval** is
 * specified, then **y1** and **y2** are derived from **y**, representing the
 * lower and upper bound of the containing interval, respectively. Otherwise, if
 * only one of **y1** or **y2** is specified, the other defaults to **y**, which
 * defaults to zero.
 *
 * The optional **x** ordinal channel specifies the horizontal position; it is
 * typically bound to the *x* scale, which must be a *band* scale. If the **x**
 * channel is not specified, the waffle will span the horizontal extent of the
 * plot’s frame. Because a waffle represents a discrete number of square cells,
 * it may not use all of the available bandwidth.
 *
 * If *options* is undefined, then **x** defaults to the zero-based index of
 * *data* [0, 1, 2, …], allowing a quick waffle chart from an array of numbers:
 *
 * ```js
 * Plot.waffleY([4, 9, 24, 46, 66, 7])
