Greg,

Good to see you’re still playing around with neo4j.

This is a little job I cooked up (yes, it’s in PHP), but it might be of interest for reverse engineering purposes: https://github.com/jgillmanjr/graphNav

Basically, clicky drag-drop way to edit the data.

I also created a docker container for it as well (used it as an excuse to play around with docker a while back). https://hub.docker.com/r/jgillmanjr/graphnav/
