heatmap
Gets the kernel density estimation of a pixel in a heatmap layer, which is a relative measure of how many data points are crowded around a particular pixel. Can only be used in the `heatmap-color` property.
Example usage:
HeatmapLayer layer = new HeatmapLayer("layer-id", "source-id");
layer.setProperties(
heatmapColor(interpolate(linear(), heatmapDensity(),
literal(0), rgba(33, 102, 172, 0),
literal(0.2), rgb(103, 169, 207),
literal(0.4), rgb(209, 229, 240),
literal(0.6), rgb(253, 219, 199),
literal(0.8), rgb(239, 138, 98),
literal(1), rgb(178, 24, 43))
)
);
