Embedding an arbitrary Wikidata property value edit
Since Los Angeles is item Q65 in Wikidata, and since "population" is property P1082 in Wikidata, I can tell you that, according to Wikidata, the population of Los Angeles is 3,898,747.
That number in bold up there was produced with the following wikicode: {{#property:P1082|from=Q65}}.
(more examples TBD)
