Adding data to a graph in DataStax Studio

Steps to add data to a graph by writing and executing Gremlin code in Gremlin cells in a notebook.

1. Add four more vertices and two other edges:

   user = graph.addVertex(label, 'user', 'id', 2, 'name', 'Jay Quest', 'role', 'customer')
   product = graph.addVertex(label, 'product', 'id', 3, 'name', 'digital camera')
   user.addEdge('bought', product)
   
   user = graph.addVertex(label, 'user', 'id', 3, 'name', 'Bartholmew Hicks', 'role', 'employee')
   product = graph.addVertex(label, 'product', 'id', 4, 'name', 'eraser')
   schema.edgeLabel('manufactured').create()
   user.addEdge('manufactured', product)
   
   g.V()

   

2. Create an edge between two existing vertices:
   1. Add this code to a new Gremlin cell:

      user = g.V().has('user', 'name', 'Jo Dowe').next()
      product = g.V().has('product', 'name', 'eraser').next()
      user.addEdge('bought', product)
      
      g.V()
      

   2. Switch the cell to display a graph.
   3. Select the Jo Dowe user vertex.
