    * Generate values and color swatches mapping for a given interval classmap.

+   * Returns a color map for intervals, where each interval is defined by:
+   * - A numeric range `[min, max]` representing the interval boundaries.
+   * - An RGBA color `[red, green, blue, alpha]` associated with the interval.
+   *
+   * The response is a 2D array of interval definitions, where each element is a pair:
+   * - The first element is an array of two numbers `[min, max]` defining the interval.
+   * - The second element is an array of four numbers `[red, green, blue, alpha]` defining the RGBA color.
+   *
+   * Example:
+   * ```json
+   * [
+   *   [
+   *     [-2, 0], [0, 0, 0, 0]

+   * - The interval `[-2, 0]` is mapped to the color `[0, 0, 0, 0]` (transparent black).
+   * - The interval `[1, 32]` is mapped to the color `[255, 255, 178, 255]` (opaque yellow).
