The container can be an svg or any g elements. * **size([width, height])** - Sets this map's dimensions to specified width and height and returns this map. * **style(style)** - Overrides the default styles and return this map. * style.**transition**: a boolean value that turns on/off the transition effect * style.**shape**: the shape of map cells - square or circle * style.**sizeByValue**: all the cells have the same size by default. The map will calculate cell size based on its value if you enable this option. * style.**cr**: the attribute defines a radius on both x and y axes of rectangular map cells. The default is 4. * style.**defaultCellColor**: the default color of map cells * style.**defaultTextColor**: the default color of map cell labels * style.**shortFormat**: the default short format of the number displays inside the cell * style.**longFormat**: the default long format of the number displays below the cell when the user hovers mouse over * style.**legendFormat**: the number format of map legend * style.**legendTitle**: the title of the map legend * style.**showOverlay**: a boolean value that turns on/off the overlay (mini charts) * style.**showOverlayLegend**: a boolean value that determines whether the overlay legend is enabled * style.**overlayLegendThreshold**: the threshold of the overlay legend * style.**showMapLegend**: a boolean value that determines whether the map legend is enabled * style.**alwaysShowOverlay**: a boolean value that determines whether the overlay is always displayed or not * style.**hideCell**: a boolean value that determines whether the cell itself is visible or not. It's a combination option and should be used with the **alwaysShowOverlay** for displaying overlay with a clean background. * **cellPalette(palette)** - Sets the color palette of cells to a specified continuous interpolator and returns this map. Default is d3.interpolateYlGnBu. * **overPalette(palette)** - Sets the color palette of the overlay to a specified categorical scheme and returns this map. Default is d3.schemeTableau10. * **mapGrid(map)** - Sets the map grid data and returns this map. The grid data can be easily generated by using the **MapEditor** below. * **data(data)** - Sets the data and returns this map. * **field(field)** - Sets the field names of map subdivision code, name, and values. * field.**code**: the field name of subdivision code * field.**name**: the field name of subdivision name * field.**values**: an array of field names specifying from which fields the map can gather data when rendering mini charts * field.**total**: the field name of subdivision value. It is optional if you have specified the field.values unless you need to show a different number other than the total. * **customSquareOverlay(f)** - Sets the custom function for overriding the square overlay renderer. There are three arguments for the custom function: * **g** - the g element contains the mini chart * **getSize** - the function to get the size of the mini chart. It is only needed when you customize the overlay with *style.sizeByValue* turned **on**. * **color** - the color scale of the values * **customCircleOverlay(f)** - Sets the custom function for overriding the circle overlay renderer. * **processMap()** - This is only needed when you customize the overlay with *style.sizeByValue* turned **off**. For details, please see the tutorial above. * **render()** - Renders the map and returns this instance.`4a:T5787,class GridMap { constructor(container) { this._container = container; this._g = null; this._width = 800; this._height = 600; this._style = { transition: false, shape: "square", sizeByValue: false, cr: 4, defaultCellColor: "#999", defaultTextColor: "white", shortFormat: ".2s", longFormat: ",.0d", legendFormat: ",.0d", legendTitle: "", showOverlay: true, showOverlayLegend: true, alwaysShowOverlay: false, showCellText: true, hideCell: false, overlayLegendThreshold: 14, showMapLegend: true }; this._cellPalette = d3.interpolateYlGnBu; this._textPalette = d3.interpolateCubehelixDefault; this._overlayPalette = d3.schemeTableau10; this._gridData = null; this._cols = 0; this._rows = 0; this._x = null; this._y = null; this._bandwidth = { x: 0, y: 0, hx: 0, hy: 0 }; this._data = null; this._chartData = null; this._field = { code: "code", name: "state", values: [], total: "" }; this._contains = { data: true, values: true }; this._c = null; // cell color scale this._t = null; // text color scale this._ov = null; // overlay mini chart color scale this._fullOpacity = 1; this._showLabel = true; this._initDuration = 500; this._miniLegend = null; this._mapLegend = null; this._customSquareOverlay = null; this._customCircleOverlay = null; this._onMouseEnter = null; this._onMouseLeave = null; this._onClick = null; this._uniqueId = new String(Date.now() * Math.random()).replace(".", ""); } size(_) { return arguments.length ?
