It would be good to have somewhere central that tabular datasets could be uploaded to -- eg the data to be plotted by the graphs extension.
The data should be uploadable and exportable in a variety of standard formats -- eg CSV, TSV, JSON, XML -- and stored in a format-neutral way.
Wikidata is great for single values, or values to be scattered across multiple items, but it's not so good for data in a systematic 1-dimensional or 2-dimensional form.
