I successfully installed and populated a local Wikibase instance via Docker, following @Addshore's instructions. Everything seems to work smoothly, except that the graph plugin doesn't render results. It is greyed out as a visualization option in the menu when I run a query that returns graph-compatible results.
I created several items in my local instance connected via property P5 ("child"). The following query returns several results, formatted according to the Graph specs:
# #defaultView:Graph
SELECT ?parent ?parentLabel ?child ?childLabel WHERE {
?parent wdt:P2 wd:Q3. #parents should be an instance of humans
?parent wdt:P5 ?child. #parents link to children via P5 ("child") property
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}These are the results in table view:
The Graph option is greyed out and I don't understand why. If I try and force a Graph layout I get an empty screen. Other visualization options seem to work fine.
I am on Mac OS High Sierra and this doesn't see to be a browser specific issue. cc @Jonas
