I put Jev to use in an example for "graph navigation" (inspired by the wikilinks demo) - connect to existing neo4j database - starting point - give a goal (target node, general isntructions, or path intent) - have Jev see each relationship + neighbor via Choice and give probabilities for following them - pick the top one(s), repeat, check with a boolean/noul if goal is reached - repo https://github.com/jexp/neo4jev (w/ code, jupyter, streamlit)
