To simultaneously be more specific (because there are other .csv paths) and be more general (because a dataset may not always be a .csv)

Probably not a good idea to heavily overload the semantics of this argument--e.g. by allowing dataset_path to be any of 12 different things--but it repeatedly annoys me that the name csv_path is not very clear from context.
Maybe dataset_csv_path? But that's starting to get pretty verbose
