Why are lines not showing between stages tasks in gitlab ci?

Question

GitLab

I apologize for my naivety, I'm just learning gitlab.
In all sources, lines are drawn between jobs, but in my environment for some reason they are not.
Perhaps there is some parameter? Or is it a Gitlab revision? I have CE, maybe where the lines are EE?
where only build and test are mine, the second picture is from the Internet.

need to define needs.
successive task execution dependencies
however, this has negative consequences, for example, ignoring the conditions of the tasks.
