Creating A Sample User Graph

We want to create a social network, and have to connect some people. Let’s do that in two steps.

Create a few users

UNWIND ["Amanda","Michael", "Max","Magnus","Mark","Peter","Andres"] AS name
CREATE (:User {name:name})

Connecting users starting with M

MATCH (u:User)
WHERE u.name =~ 'M.*'
WITH collect(u) as users

UNWIND users AS u1
UNWIND users[1..] AS u2

create (u1)-[:knows]-> (u2)
