I think that Observable is a great tool to explore Wikidata.
Wikidata is a collaborative knowledge base. It’s a sister project for Wikipedia. Each Wikipedia article is linked to a Wikidata item. For instance, the Wikipedia article about [Florence Nightingale] (Florence - Wikipedia Nightingale) is linked to a Wikidata item. Of course, the big advantage of Wikidata is that data is structured. It can be queried using https://query.wikidata.org/ which uses the SPARQL syntax. Query.wikidata.org is very powerful but limited if you want to draw a visualisation or tell a story with the data.
@piecesofuk has a nice notebook exploring UK government : UK Parliament: Cabinet Ministers / piecesofuk / Observable
Since I really believe that Observable is great to explore Wikidata, I’ve written a small introduction for Wikidata users: An introduction to Observable for Wikidata users / PAC / Observable
I also have some examples:
- Women and Nobel prize : Women and Nobel prize / PAC / Observable
- All tour de France’s stage winners from 1903 to today : Tour de France's stage winners / PAC / Observable
- A tool to explore gender biased labels in Wikidata : Are occupation labels in Wikidata gender neutral? / PAC / Observable
- A tool to explore all statements about one item : Wikidata's Q item explorer / PAC / Observable
Of course Wikidata and SPARQL are also useful to explore Wikipedia:
- We can explore featured articles in Wikipedia in French : Celebrating the 2,000 featured articles milestone in Wikipedia in French / PAC / Observable
- It can also be used to explore gender diversity in Wikipedia articles Gender diversity in Wikipedia articles: evidence from some selected academic disciplines in the English Wikipedia / PAC / Observable and Explore gender diversity in a single Wikipedia article / PAC / Observable.
I’m sure that there are lots of other great examples and I’d really be interested in creating more bridges between Observable and Wikidata communities.
