185 OD replies: Besides being able to display data without prior knowledge of the
186 kind of data inside a dataset, is there any reason to put this within the
187 dataset class? If not, it seems to me it may be more appropriate to have a way
188 for the dataset to describe the kind of data it holds, and keep the
189 visualization code separate from the dataset itself. It would make it easier
190 in particular to try different visualization systems, and description of the
191 data may turn out to be useful for other reasons (however, it also means we'd
192 need to come up with a good way to describe data, which could prove
193 difficult).
