What do you mean by "first"? First in what sense?

By understanding the code, then--there's no "flow" in a class diagrams. Class diagrams show entity relationships.

A class diagram is a hierarchical vision of the domain in terms of dumb data structures.
How you do know what is a root class in that diagram really depends on the use case.
Client entity might be the first (ROOT) class for the use case of a Client Moving from Address A to Address B.

The trick I use to immediately see the behavior of my class diagram is a good reverse engineering.
If you display the project dependencies then you can see from which classes are coming dependencies .
I found this image of a dependencies detection: http://www.forum-omondo.com/documentation_eclipseuml_2008/reverse/reverse/open_existing_diagram.png
sometimes you only have one class and hundred of dependencies going out from the same class then it is easier to identify the central class
