This Tableau WDC implements WDC v2.3.0 and can be used with Tableau v10.4 or later and Neo4j v3.0.4 or later:
https://tableau.github.io/webdataconnector/docs/wdc_library_versions
For details on Tableau's Web Data Connector and the WDC SDK please visit:

The Neo4j WDC uses the Neo4j Driver for Javascript v1.7 which implements the Bolt network protocol:
https://github.com/neo4j/neo4j-javascript-driver
- Neo4j Temporal values
- converts Neo4j Date and DateTime values to Tableau Date or DateTime
- converts Neo4j Time values to Tableau Integer (seconds of the day)
- doesn't convert Neo4j Duration values but creates separate columns for all parts (months, days, seconds, nanoseconds)
- Neo4j Spatial values
- converts Neo4j Point values to Tableau Geometry (GeoJSON)
The Neo4j WDC v2.3 can be used online via hosted GitHub page. Here is the WDC URL you can copy to your Tableau client:
http://ralfbecher.github.io/tableau-neo4j-wdc/v2.3/Neo4jWdc2.html (copy URL)
- Data Source Name: the name for the data source in the Tableau Workbook
- Neo4j URL: URL to connect a Neo4j server, usually
bolt://<server>when default Bolt port orbolt://<server>:<port> - Username/Password: authentication credentials
- Inspect Rows for Schema: number of sample rows (default: 1000) to inspect JSON result set (can contain complex objects) from Cypher queries for used properties, important to build the table schema with columns for Tableau; set to 1 when first row includes all properties
- Cypher Queries: a list to add up to 5 Cypher queries for execution; use a table name per query in left column; tables can then be joined in Tableau data wizard later
The Neo4j WDC v1.0 can still be used via new URL:
http://ralfbecher.github.io/tableau-neo4j-wdc/v1/Neo4jWdc.html
