I am having the same issue. Using Neo4j 4.3.2 Community Edition. (And like Rob, other graph visualization works just fine.)
Further, I found that with
CALL db.schema.visualization YIELD nodes I get a graphical view of the nodes, but if I instead write
YIELD relationships or
YIELD nodes, relationships, it reverts back to the text output.
@rob2 or anyone else, have you found a solution here?
I stumbled on the same issue for Neo4j 4.3 and found a passable solution.
CALL db.schema.visualization returns two separate lists with nodes and relationships and I suspect that this is preventing the browser from parsing the data as a graph. So I used
UNWIND to expand them in separate rows.
CALL db.schema.visualization() YIELD nodes, relationships UNWIND relationships as r UNWIND nodes as n RETURN r, n
