There's a lot of discussion here of the 'western lens' as you bring up, but I'm not sure that's fair criticism. The creator(s) aggregated data and built something very interesting. To complain that the data they used isn't universal doesn't seem fair. I think Wikipedia is a reasonable starting place, but yes, Wikipedia skews geographically.

All datasets have bias. It's okay to acknowledge that and still find insights in the data.

Honestly curious: what highly accessible dataset that allows for the simple creations of 'fame metrics' would be better? I'm not aware of any.
