Manage your graphs

The graph module provides functions dealing with graph structures. Examples will explain the REST API on the social graph:

Social Example Graph

List all graphs

Lists all graphs known to the graph module.

GET /_api/gharial

Lists all graphs stored in this database.

  • graphs (array):

    • graph (object): The information about the newly created graph
