Magnus Manske just sent this message to another list and I thought you'd
want to know. Baglama is a tool to "View counts for pages using Commons
images in certain category trees." It's especially useful for GLAM
institutions: https://outreach.wikimedia.org/wiki/GLAM

Due to popular demand, my "baglama" tool now has charts for all
projects on its main page, and a project chart on the project page,
with the selected month highlighted. The bars are relative to the
maximum monthly view counter in the project. Enjoy.
