/**
* Divides the plane into a grid and color the bins by the count of cases in them.
*
* By default, this geom uses `coordFixed()`.
* However, this may not be the best choice when the values on the X/Y axis have significantly different magnitudes.
* In such cases, try using `coordCartesian()`.
*
* ## Notes
*
* Computed variables:
*
* - ..count.. : number of points with coordinates in the same bin.
*
* ## Examples
*
* - [density_2d.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/density_2d.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.bin2D()`. 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 bins default = Pair(30, 30).
* Number of bins in both directions, vertical and horizontal. Overridden by `binwidth`.
* @param binWidth The width of the bins in both directions, vertical and horizontal. Overrides `bins`.
* The default is to use bin widths that cover the entire range of the data.
* @param drop default = true.
* Specifies whether to remove all bins with 0 counts.
* @param x X-axis value.
* @param y Y-axis value.
* @param width Width of a tile.
* @param height Height of a tile.
* @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 Fill color.
* For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
* @param linetype Type of the line.
* Accept codes or names (0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash"),
* a hex string (up to 8 digits for dash-gap lengths),
* or a pattern `offset to listOf(dash, gap, ...)` / `listOf(dash, gap, ...)`.
* For more info see: [aesthetics.html#line-types](https://lets-plot.org/kotlin/aesthetics.html#line-types).
* @param size Line width, default = 0 (i.e. tiles outline initially is not visible).
* @param weight Used by `Stat.bin2D()`stat to compute weighted sum instead of simple count.
* @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".
