The type of a column of values, as px decides from pandas dtypes: numeric when every present value is a number (or bigint), date when every present value is a Date or an ISO-8601 date string (2024-03-01, 2024-03-01 12:30, …), else categorical (strings, booleans, mixes, and columns with no present value). Missing values (null, undefined, NaN) are ignored; numeric strings are categories, as in pandas (fromCSV parses numbers first).
