// Create an instance of the "Modern" toy graph

graph = TinkerFactory.createModern()

// Create the traversal source

g = graph.traversal()

// Get all vertices

g.V()

// Get the vertex with the ID "1"

g.V(1)

// Get the value of the "name" property on the vertex with the ID "1"

g.V(1).values('name')

// Start from the vertex with ID "1" and get the outgoing edges labeled "knows"

g.V(1).outE('knows')

// Get the names of the people vertex "1" knows (long version)

g.V(1).outE('knows').inV().values('name')

// Get the names of the people vertex "1" knows (concise version)

g.V(1).out('knows').values('name')

// Get the names of the people vertex "1" knows who are over the age of 30

g.V(1).out('knows').has('age', gt(30)).values('name')
