Adding a Vertex

You can use a specific API provided by GES to add a vertex. The sample code is as follows:

 public static void addVertex(GraphClient graphClient) throws ApiException
{
    Map properties = new HashMap();
    List male = new ArrayList();
    gender.add("F");
    properties.put("Gender", gender);
    List occupation = new ArrayList();
    occupation.add("artist");
    properties.put("Occupation", occupation);
    List age = new ArrayList();
    age.add("under 18");
    properties.put("Age", age);
    List zipCode = new ArrayList();
    zipCode.add("98133");
    properties.put("Zip-code", zipCode);
    AddVertexReq req = new AddVertexReq();
   //Set the vertex ID.
    req.setVertexId("Lily");
    //Set the label. 
    req.setLabel("user");
    //Set the properties.
    req.setProperties(properties);
    graphClient.addVertex(req);

}
