Wow this is surprisingly useful to explore local data, thanks for building!!
I wonder: why are you calculating PageRank, are the wiki article views not enough?
If I play around with the importance slider, PageRank seems to have much less difference between articles, highlighting just a few articles per city in large text.
Yes, the pageview statistics might be enough, but I started from the pagerank dataset https://github.com/athalhammer/danker
And because of bot traffic, the pageview statistics are sometimes suspicious and noisy.
