This function is needed to perform a validation on a graph schema. The validateSchema function compares the output against the JSON schema.

`js
import { validateSchema } from "@neo4j/graph-schema-utils";

validateSchema(jsonSchema, graphSchema);
`

You can also create a schema model programatically.
Example:

`js
import { model } from "@neo4j/graph-schema-utils";

const labels = [
new model.NodeLabel("l1", "Person"),
new model.NodeLabel("l1", "Movie"),
];

const relationshipTypes = [new model.RelationshipType("rt1", "ACTED_IN")];

const properties = [
new model.Property("name", new model.PropertyBaseType("string"), true),
new model.Property("title", new model.PropertyBaseType("string"), true),
new model.Property(
"roles",
new model.PropertyArrayType(new model.PropertyBaseType("string")),
false
),
];

const nodeObjectTypes = [
new model.NodeObjectType("n1", [labels[0]], [properties[0]]), // (:Person {name}) node type
new model.NodeObjectType("n2", [labels[1]], [properties[1]]), // (:Movie {title}) node type
];

const relationshipObjectTypes = [
// (:Person {name})-[:ACTED_IN {roles}]->(:Movie {title})
new model.RelationshipObjectType(
"r1",
relationshipTypes[0],
nodeObjectTypes[0],
nodeObjectTypes[1],
[properties[2]]
),
];

const graphSchema = new model.GraphSchema(
nodeObjectTypes,
relationshipObjectTypes
);
