It's so common to use histograms in data science. Why not ?
And its just some code like this
{min, max} = enumerable |> Enum.min_max()
interval_size = max - min
buckets = oṕts(:buckets_number)
bucket_size = interval_size / buckets
enumerable
|> Enum.frequencies_by(fn element -> trunc((element - min)/bucket_size) end)
|> Enum.map(fn {key, frequency} ->
bucket_min = (key*bucket_size) + min
bucket_max = min(max,bucket_min + bucket_size)
{{bucket_min, bucket_max}, frequency }
end)
