I am unfamiliar with Neo4 and want to find out whether it is the right tool for me. Is it possible to nest nodes in a hierarchy of subgraphs/clusters as in this GraphViz graph? If so, what would the Cypher query be to create that graph?
Hi, I'm trying to use the APOC Extended Plugin. Unfortunately, the database is unavailable (it says with sysinfo that the neo4j status is offline) when the plugin is installed. Neo4j Desktop display that the DBMS is active, so I can open It with Neo4...
Forgive me if this is not the correct place to ask a question about cypher queries. I'm extremely new to neo4j and am curious if anyone has solved this problem before. I've got a graph of parent/child relationships which form a tree of Person nodes....
My simple 4 node graph is: (thing:Steve) -[is]-> (thing:Person) -[does]-> (action:living) <-[is]- (action:breathing) but this query MATCH (a:thing),(b:action)OPTIONAL MATCH (a)-[r]-(b)OPTIONAL MATCH (a)-[r1]-(a)OPTIONAL MATCH (b)-[r2]-(b)return * ret...
