Another way to do so is by using `UNWIND`. Suppose I have 6 vertices:
```
(:Person {name: 'Joe', title: 'Developer'}),
(:Person {name: 'Andy', title: 'Manager'}),
(:Person {name: 'Hakan', title: 'Protector'}),
(:Person {name: 'Leyla', title: 'Assistant'}),
(:Person {name: 'Sofi', title: 'Explorer'}),
(:Person {name: 'Ian', title: 'Scientist'})
```
Now, I can use `UWIND` to create edges for these with a single cypher query.
See example below:
```
SELECT * FROM cypher('test', $$
WITH [
{source: 'Joe', target: 'Andy', weight: 2},
{source: 'Andy', target: 'Hakan', weight: 3},
{source: 'Andy', target: 'Leyla', weight: 1},
{source: 'Hakan', target: 'Sofi', weight: 4},
{source: 'Sofi', target: 'Ian', weight: 2}
] AS edges
UNWIND edges AS edge
MATCH (source:Person {name: edge.source})
MATCH (target:Person {name: edge.target})
CREATE (source)-[rel:WORKS_WITH {weight: edge.weight}]->(target) RETURN rel
$$) as ( a agtype);
```
