"getting started" differs from "basic example"

[Kebap]

Issue:
The "getting started" section on the "network" website shows four (4) edges, but the following link to the "basic example" shows five (5) edges. The edge missing connects node 3 to itself. This is opposed to the claim "The result of the code above will be the basic example which is shown here."

Suggested fix:
Include fifth edge in website here:
