/**
* A violin plot is a mirrored density plot with an additional grouping as for a boxplot.
*
* ## Examples
*
* - [geom_violin.ipynb](https://nbviewer.jupyter.org/github/JetBrains/lets-plot-kotlin/blob/master/docs/examples/jupyter-notebooks/geom_violin.ipynb)
*
* - [violin_tails_cutoff.ipynb](https://nbviewer.jupyter.org/github/JetBrains/lets-plot-kotlin/blob/master/docs/examples/jupyter-notebooks/violin_tails_cutoff.ipynb)
*
* - [violin_show_half.ipynb](https://nbviewer.jupyter.org/github/JetBrains/lets-plot-kotlin/blob/master/docs/examples/jupyter-notebooks/violin_show_half.ipynb)
*
* - [quantile_parameters.ipynb](https://nbviewer.jupyter.org/github/JetBrains/lets-plot-kotlin/blob/master/docs/examples/jupyter-notebooks/f-4.3.0/quantile_parameters.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 default = `Stat.yDensity()`. 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 default = `positionDodge()`. 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 sampling Result of the call to the `samplingXxx()` function.
* To prevent any sampling for this layer pass value `samplingNone`.
* For more info see [sampling.md](https://github.com/JetBrains/lets-plot-kotlin/blob/master/docs/sampling.md).
* @param tooltips Result of the call to the `layerTooltips()` function.
* Specifies appearance, style and content.
* @param orientation Specifies the axis that the layer's stat and geom should run along, default = "x".
* Possible values: "x", "y".
* @param quantiles Draw horizontal lines at the given quantiles of the density estimate.
* @param quantileLines default = false.
* Show the quantile lines.
* @param showHalf default = 0.
* - If -1 then it's drawing only half of each violin.
* - If 1 then it's drawing other half.
* - If 0 then violins looking as usual.
* @param x X-axis coordinates.
* @param y Y-axis coordinates.
* @param violinWidth Density scaled for the violin plot, according to area, counts or to a constant maximum width.
* @param alpha Transparency level of a layer. Understands numbers between 0 and 1.
* @param color Color of the geometry.
* String in the following formats:
* - RGB/RGBA (e.g. "rgb(0, 0, 255)")
* - HEX (e.g. "#0000FF")
* - color name (e.g. "red")
* - role name ("pen", "paper" or "brush")
*
* Or an instance of the `java.awt.Color` class.
* @param fill Fill color.
* String in the following formats:
* - RGB/RGBA (e.g. "rgb(0, 0, 255)")
* - HEX (e.g. "#0000FF")
* - color name (e.g. "red")
* - role name ("pen", "paper" or "brush")
*
* Or an instance of the `java.awt.Color` class.
* @param linetype Type of the line of border.
* Codes and names: 0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash",
* 5 = "longdash", 6 = "twodash".
* @param size Lines width.
* Defines line width.
* @param width Width of violin bounding box.
* @param weight Used by `Stat.yDensity()` stat to compute weighted density.
* @param scale default = "area".
* - If "area", all violins have the same area.
* - If "count", areas are scaled proportionally to the number of observations.
* - If "width", all violins have the same maximum width.
* @param tailsCutoff default = 3.0.
* Extends domain of each violin on `tailsCutoff * bw` if `trim = false`.
* @param bw String or Double.
* The method (or exact value) of bandwidth. Either a string (choose among "nrd0" and "nrd") or a double.
* @param kernel The kernel we use to calculate the density function. Choose among "gaussian", "cosine", "optcosine",
* "rectangular" (or "uniform"), "triangular", "biweight" (or "quartic"), "epanechikov" (or "parabolic").
* @param n The number of sampled points for plotting the function.
* @param trim default = true.
* Trims the tails of the violins to the range of the data.
* @param adjust Adjusts the value of bandwidth by multiplying it. Changes how smooth the frequency curve is.
* @param fullScanMax Maximum size of data to use density computation with "full scan".
* For bigger data, less accurate but more efficient density computation is applied.
* @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".
