Problem

For the most part I (and I assume most people) end up at any given example in the gallery through some combination of googling somewhat incoherent phrases and links out from stackoverflow. This actually works great due to the breadth of topics covered in the examples. However there is no natural path for a reader to discover related examples.
e.g. If I end up on https://matplotlib.org/devdocs/gallery/statistics/histogram_features.html#sphx-glr-gallery-statistics-histogram-features-py

then there is no easy way to find the other histogram examples, or even to know that others exist. This is a shame as there are many other histogram examples:

This is especially so because of however the examples get placed into the toctree the next level up from the example page is the contents page rather than the list of examples:

I think that at least part of #19221 is a special case of this general issue.

Suggested Improvement

Implement a standard section in all examples for Related Examples or Further Reading or something to that effect. Then slowly implement this over all the examples and require it in all future examples.

This could be done already, but it would be very nice to have a standard set for how to do this.
