A standalone tool to find the source cat for why a given image is in a specific category tree

[prototyperspective]

The tool has a feature that shows why a specific image is located somewhere underneath a specific category (the category where the Quality images button was clicked) as shown in the screenshot.

As noted here, it would be great if there was a tool where could enter a file and a category and it would show the path/s why it's in that cat (or a gadget by which one can do so via a dropdown at the respective file or category page).

For example, I wanted to find out why chart Life_expectancy_in_Albania.svg was somewhere in the category tree of Category:Maps of the world.

I guess close this early or move it to Discussions if there are some for this repo since it's not about the gadget itself, but it would be great if you could do this since the code for this seems to largely already exist here.
