/**
* Draws pie chart.
*
* ## Notes
*
* Computed variables:
*
* - ..count.. : number of points with same (x,y) coordinate.
* - ..sum.. : total number of points with same (x,y) coordinate.
* - ..prop.. : groupwise proportion.
* - ..proppct.. : groupwise proportion in percent.
* - ..sumprop.. : proportion of points with same (x,y) coordinate among all points in the dataset.
* - ..sumpct.. : proportion of points with same (x,y) coordinate among all points in the dataset in percent.

*
* @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.count2d()`. 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 inheritAes default = true.
* false - do not combine the layer aesthetic mappings with the plot shared mappings.
* @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 labels Result of the call to the `layerLabels()` function.
* Specifies style and content of the annotations.
* @param map Data-structure containing series of planar shapes and, optionally, associates 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 slice Values associated to pie sectors.
* @param explode Values to explode slices away from their center point, detaching it from the main pie.
* @param size Pie diameter.
* @param fill Fill color.
* For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
* @param alpha Transparency level of a layer. Understands numbers between 0 and 1.
* @param color Color of inner and outer arcs of pie sector.
* For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
* @param stroke Width of inner and outer arcs of pie sector.
* @param weight Used by `Stat.count2d()` stat to compute weighted sum instead of simple count.
* @param hole default = 0.0.
* A multiplicative factor applied to the pie diameter to draw donut-like chart.
* Understands numbers between 0 and 1.
* @param strokeSide default = "both" ("outer", "inner", "both").
* Defines which arcs of pie sector should have a stroke.
* @param spacerWidth default = 0.75.
* Line width between sectors.
* Spacers are not applied to exploded sectors and to sides of adjacent sectors.
* @param spacerColor Color for spacers between sectors. By default, the "paper" color is used.
* For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
* @param sizeUnit Relates the size of the pie chart to the length of the unit step along one of the axes.
* Possible values: "x", "y". If not specified, no fitting is performed.
* @param fillBy default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c").
* Defines the fill aesthetic for the geometry.
* @param colorBy default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c").
* Defines the color 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".
