AFAIK, you can query data from Wikidata, but you cannot put it into a page, unless its a graph. Graphs can do it - https://www.mediawiki.org/wiki/Extension:Graph/Demo/Sparql
As of last Thursday, you can also create a table on Commons Data namespace, and make a simple Lua script on your favorite wiki to pull that data in and render it. Since Wikidata is accessible from Lua, you could pull useful information about each president. I am not sure about the efficiency aspects here.
WeatherDemo https://en.wikipedia.org/wiki/User:Yurik/WeatherDemo -- pulls data from commons Data:Weather/New_York_City.tab https://commons.wikimedia.org/wiki/Data:Weather/New_York_City.tab and formats it using enwiki module https://en.wikipedia.org/wiki/Module:Sandbox/Yurik. I'm still working on some fun demos for a big presentation.

Hi.
If I wanted to make a page on the English Wikipedia using wikitext called "List of United States presidents" that dynamically embeds information from https://www.wikidata.org/wiki/Q23 and https://www.wikidata.org/wiki/Q11806 and other similar items, is this currently possible? I consider this to be arbitrary Wikidata querying, but if that's not the correct term, please let me know what to call it.
A more advanced form of this Wikidata querying would be dynamically generating a list of presidents of the United States by finding every Wikidata item where position held includes "President of the United States". Is this currently possible on-wiki or via wikitext?
If either of these querying capabilities are possible, how do I do them? I don't understand how to query Wikidata in a useful way and I find this frustrating. Since 2012, we've been putting a lot of data into Wikidata, but I want to programmatically extract some of this data and use it in my Wikipedia editing. How do I do this?
If these querying capabilities are not currently possible, when might they be? I understand that cache invalidation is difficult and that this will need a sensible editing user interface, but I don't care about all of that, I just want to be able to query data out of this large data store.
