/**
* Scales for alpha aesthetic.
*
* @param range The range of the mapped aesthetics result.
* @param name The name of the scale - used as the axis label or the legend title. If null, the default, the name of the scale
* is taken from the first mapping used for that aesthetic.
* @param breaks A list of data values specifying the positions of ticks,
* or a dictionary which maps the tick labels to the breaks values.
* @param labels A list of labels on ticks, or a dictionary which maps the breaks values to the tick labels.
* @param lablim The maximum label length (in characters) before trimming is applied.
* @param limits A numeric vector of length two providing limits of the scale.
* @param naValue An aesthetic value which is used when data in not available.
* @param format Specifies the format pattern for labels on the scale.
* @param guide Guide to use for this scale.
* It can either be a string ("colorbar", "legend") or a call to a guide function (`guideColorbar()`, `guideLegend()`)
* specifying additional arguments.
* "none" will hide the guide.
* @param trans Name of built-in transformation ("identity", "log10", "log2", "symlog", "reverse", "sqrt").
*
* Format patterns in the `format` parameter can be just a number format (like "d") or
* a string template where number format is surrounded by curly braces: "{d} cylinders".
* Note: the "$" must be escaped as "\$".
* For more info see: [formats.html](https://lets-plot.org/kotlin/formats.html)
*
* Examples:
* - ".2f" -> "12.45";
* - "Score: {.2f}" -> "Score: 12.45";
* - "Score: {}" -> "Score: 12.454789".
