Fun with apk...
Install the graphviz package on your workstation (apt/dnf install graphviz, Windows installers available here: https://graphviz.org/download/).
Pick a package, here I'm using nmap, and run apk dot package. Push the resulting .dot file through Graphviz's dot converter, here I'm generating a png.
ssh router "apk dot nmap" | dot -Tpng -o nmap-dependencies.png
