GLAMorgan is a tool by Magnus Manske to produce Wikimedia Commons pageviews for a given category, similar to BaGLAMa but on demand.
Problem: GLAMorgan is majorly affected by ad blockers! Do not use the tool from a browser with ad blocking on.
Turn off ad blocking, or use a browser profile that doesn't use it.
Otherwise, you will not see any pageview statistics, and you will see numerous errors such as: "Data for X pages could not be loaded from the WMF pageview API (404 error)."
- wikitech:Pageviews API (which made this tool possible in 2016)
- TreeViews (for categories of articles, rather than files)
