Paul,
You can use relationships to model came-before, like so:
http://console.neo4j.org/r/owv0da
Probably simplistic, but wanted to show you http://console.neo4j.org ;)

Something like http://console.neo4j.org/?id=4p9jvt perhaps?
Where you have users performing actions, where you insert a middle node for each action which points to the action as well as the next action in line. The user node has a relationship to the last middle node where new actions gets appended. Such a middle node could have a time stamp also.

Yep a secondary graph structure of a linked list is usually what you use for this.
Probably combined with a time-tree index structure for easier access of time intervals or points in time:

There used to be a good time series graph doc somewhere too yes?

Yes,
a timeline implementation is here:
