When a Data File has been Imported, the program should verify if the file's columns contain NaNs. Upon the case that an entire column is filled with non-useful data (whether NaNs, nulls, or empty spaces ["", " ", or the like]), the program should reply with a window stating "The column lacks any valid data. It will not be shown as a graphable column" and will not include it in the HeaderData object.
