/**
 *  Adds a text directly to the plot with a rectangle behind the text.
 *
 * ## Examples
 *
 * - [geom_label.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/geom_label.ipynb)
 *
 * - [geom_label_alpha_stroke.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/geom_label_alpha_stroke.ipynb)
 *
 * @param data The data to be displayed in this layer. If null, the default, the data
 *  is inherited from the plot data as specified in the call to [letsPlot][org.jetbrains.letsPlot.letsPlot].
 * @param stat The statistical transformation to use on the data for this layer.
 *  Supported transformations: `Stat.identity`, `Stat.bin()`, `Stat.count()`, etc. see [Stat][org.jetbrains.letsPlot.Stat].
 * @param position Position adjustment: `positionIdentity`, `positionStack()`,
 *  `positionDodge()`, etc. see [Position](https://lets-plot.org/kotlin/-lets--plot--kotlin/org.jetbrains.letsPlot.pos/).
 * @param showLegend default = true.
 *  false - do not show legend for this layer.
 * @param manualKey String or result of the call to the `layerKey()` function.
 *  The key to show in the manual legend. Specifies the text for the legend label or advanced settings using the `layerKey()` function.
 * @param sampling Result of the call to the `samplingXxx()` function.
 *  To prevent any sampling for this layer pass value `samplingNone`.
 *  For more info see [sampling.html](https://lets-plot.org/kotlin/sampling.html).
 * @param tooltips Result of the call to the `layerTooltips()` function.
 *  Specifies appearance, style and content.
 * @param map Data-structure containing series of planar shapes and, optionally,
 *  associated data series (for example: names of States and their boundaries).
 *
 *  Supported shapes: Point and MultiPoint.
 *  All coordinates should be encoded as decimal degrees in WGS84 coordinate reference system.
 *
 *  Can be used with parameter `mapJoin` for joining data and map coordinates.
 * @param mapJoin Pair of Names or Pair of Lists of Names.
 *  Specifies column names to join the `data` and the `map` coordinates on.
 *  - Pair.first: column name or list of column names in the `data` dataframe.
 *  - Pair.second: column name or list of column names in the `map` dataframe.
 * @param useCRS By default, all coordinates are converted into degrees of longitude and latitude,
 *  and these map coordinates are projected onto the screen coordinates using Mercator projection.
 *  Specify useCRS = "provided" to keep the SpatialDataset's original coordinate reference system (CRS).
 * @param x X-axis value.
 * @param y Y-axis value.
 * @param label Text to add to plot.
 * @param alpha Transparency level of a layer.
 *  Understands numbers between 0 and 1.
 * @param color Color of the geometry.
 *  For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
 * @param fill Background color of the label.
 *  For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
 * @param size Font size.
 * @param family default = "sans".
 *  For more info see: [aesthetics.html#font-family](https://lets-plot.org/kotlin/aesthetics.html#font-family).
 * @param fontface default = "plain".
 *  For more info see: [aesthetics.html#font-face](https://lets-plot.org/kotlin/aesthetics.html#font-face).
 * @param hjust ("left", "middle", "right") or number between 0 ("left") and 1 ("right")
 *  or "inward" (aligns label towards the plot center), "outward" (away from the plot center).
 *  Horizontal label alignment.
 * @param vjust ("bottom", "center", "top") or number between 0 ("bottom") and 1 ("top")
 *  or "inward" (aligns label towards the plot center), "outward" (away from the plot center).
 *  Vertical label alignment.
 * @param angle Label rotation angle in degrees.
 * @param lineheight Line height multiplier applied to the font size in the case of multi-line text.
 * @param labelFormat Specifies the format pattern for displaying mapped values.
 * @param naText default = "n/a". Text to show for missing values.
 * @param nudgeX Horizontal adjustment to nudge labels by.
 * @param nudgeY Vertical adjustment to nudge labels by.
 * @param labelPadding Amount of padding around label. Defaults to 0.25 of font size.
 * @param labelR Radius of rounded corners. Defaults to 0.15 of label height.
 * @param labelSize default = 1.0. Size of label border.
 * @param alphaStroke default = false.
 *  Enables the applying of 'alpha' to 'color' (label text and border).
 * @param sizeUnit Relates the size of the text label to the length of the unit step along one of the axes.
 *  Possible values: "x", "y". If not specified, no fitting is performed.
 * @param colorBy default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c").
 *  Defines the color aesthetic for the geometry.
 * @param fillBy default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c").
 *  Defines the fill aesthetic for the geometry.
 * @param mapping Set of aesthetic mappings.
 *  Aesthetic mappings describe the way that variables in the data are
 *  mapped to plot "aesthetics".
 *
 *
 * Format patterns in the `labelFormat` parameter can be just a number format (like "d") or
 * a string template where number format is surrounded by curly braces: "{d} cylinders".
 * For more info see: [formats.html](https://lets-plot.org/kotlin/formats.html)
 * Note: the "$" must be escaped as "\$".
 *
 * Examples:
 * - ".2f" -> "12.45"
 * - "Score: {.2f}" -> "Score: 12.45"
 * - "Score: {}" -> "Score: 12.454789"
