Description

I don't want to start looking at the Lua that looks like it is generating this chart...

The chart shows the spread of P31/P279 throughout all wikidata items.

I believe this should be trivial to recreate using SPARQL.

SELECT (count(distinct(?s)) AS ?scount) WHERE {?s wdt:P31 wd:Q5}

etc.

Mentioned Here: P31 Fork of P29 (An Untitled Masterwork)
P279 404 and 500 error pages

@Lydia_Pintscher
The question is do we generally want to track the number of statements for each property or only for this specific use case?

We might even be able to do this from some links table rather than from SPARQL

It should be noted in the other dash we were tracking for all of them !

I am mostly interested in this particular usecase - so tracking how many items we have for the biggest categories of entities.

Done, rough graph has been added to https://grafana.wikimedia.org/dashboard/db/wikidata-datamodel for now (although this dash needs cleaning up)
