 There are a couple of things I think you might find useful (off the top
of my head):

repoquery --alldeps --whatrequires <dep>
package-cleanup --leaves
pkg-deps-tree-view.py --limit-installed <pkg> (or *, for everything)

...the later¹ is probably closest to what you want, I think, as it will
spit out deps. into a tree like format and then you can browse it.
