As an Analyst wanting to use visual ML, I'd like to be able to treat my categorical variables like Ordinal variables, Categories that have an Order. So that I can more accurately represent my features and hopefully build better models.
I believe that Sci-Kit Learn has this idea in the underlying libraries.
I fact I'd like to see this idea carried through the entire system and into charts as well.
An example might be the categories
s, m, l, xl, xxl, xxxl
There is a meaning to this order.
