Every pinout diagram has the fundamental requirement of an image to enhance with graphical additions. This prerequisite can be sizable barrier to creating the clearest diagram possible.
During pinout development several image create methods have been investigated. Community members have also reached out and generously provided feedback and further options to tryout.
Documented here is a list of what was tried during pinout development and some community input (some tried, some on my list to try out). The intent is to revisit all option and write-up some reviews and process notes.
