At some point I needed to embed a family tree visualisation on the site — something users could explore, navigate, and ideally edit inline. I assumed this would be a two-hour job. Grab a library, wire it up, done. Six hours of research later, I was starting a new repo. What's Already Out There (And Why It Wasn't Enough) The GEDCOM ecosystem GEDCOM (.ged) is the universal exchange format for genealogy data — invented by the Mormon Church in 1984, standardised in 1996, and still the format every serious genealogy tool exports to.
