SQL Server Graph Database Features

Was wondering is there a way to use or add our own queries to use SQL Server 2016-2017’s graph database features?

For example from that page the insert command for the graph would look like:

INSERT INTO FishSpecies (CommonName, ScientificName) VALUES
(‘Atlantic halibut’, ‘Hippoglossus hippoglossus’),
(‘Chinook salmon’, ‘Oncorhynchus tshawytscha’),
(‘European seabass’, ‘Morone (Decentrarchus) labrax’),
(‘Gizzard shad’, ‘Dorosoma cepedianum’),
(‘Japanese striped knife jaw’, ‘Oplegnathus faciatus’),
(‘Northern pike’, ‘Esox lucius’),
(‘Pacific herring’, ‘Clupea pallasi’),
(‘Rainbow trout’, ‘Oncorhynchus mykiss’),
(‘Sole (Dover)’, ‘Solea solea’),
(‘White bass’, ‘Morone chrysops’);

Thanks for any help guys
