Quantize scale for mapping continuous values to discrete buckets.

Divides the continuous domain into uniform segments, each mapped to a discrete value from the range. Useful for choropleth maps and heat maps where you want to bin continuous data into categories.

Examples

# Map values 0-100 to colors
scale = Visualize.Scale.Quantize.new()
  |> Visualize.Scale.Quantize.domain([0, 100])
  |> Visualize.Scale.Quantize.range(["#f7fbff", "#c6dbef", "#6baed6", "#2171b5", "#084594"])

Visualize.Scale.Quantize.apply(scale, 10)  # => "#f7fbff"
Visualize.Scale.Quantize.apply(scale, 50)  # => "#6baed6"
Visualize.Scale.Quantize.apply(scale, 90)  # => "#084594"

# Get the thresholds
Visualize.Scale.Quantize.thresholds(scale)  # => [20, 40, 60, 80]
