Interpreter configuration

Enabling the Neo4j Interpreter

Using the Neo4j Interpreter

In a paragraph, use %neo4j to select the Neo4j interpreter and then input the Cypher commands. For list of Cypher commands please refer to the official Cyper Refcard

%neo4j
//Sample the TrumpWorld dataset
WITH
'https://docs.google.com/spreadsheets/u/1/d/1Z5Vo5pbvxKJ5XpfALZXvCzW26Cl4we3OaN73K9Ae5Ss/export?format=csv&gid=1996904412' AS url
LOAD CSV WITH HEADERS FROM url AS row
RETURN row.`Entity A`, row.`Entity A Type`, row.`Entity B`, row.`Entity B Type`, row.Connection, row.`Source(s)`
LIMIT 10

The Neo4j interpreter leverages the Network display system allowing to visualize the them directly from the paragraph.

Write your Cypher queries and navigate your graph

This query:

%neo4j
MATCH (vp:Person {name:"VLADIMIR PUTIN"}), (dt:Person {name:"DONALD J. TRUMP"})
MATCH path = allShortestPaths( (vp)-[*]-(dt) )
RETURN path

produces the following result_ Neo4j - Graph - Result

Apply Zeppelin Dynamic Forms

You can leverage Zeppelin Dynamic Form inside your queries. This query:

%neo4j
MATCH (o:Organization)-[r]-()
RETURN o.name, count(*), collect(distinct type(r)) AS types
ORDER BY count(*) DESC
LIMIT ${Show top=10}

produces the following result: Neo4j - Zeppelin - Dynamic Forms
