Suggestions for a better headline graphic

Question

An answer to DBA's updated site theme is ready for testing! suggests that the headline graphic ought to be more reminiscent of an ERD diagram.

Before:

Now:

In a comment, Catija asked us to come up with a rough sketch for an improvement:

I'm not sure this can be changed now but if one of y'all could mock up an example of what might make sense for this (maybe in a new question?), I can show it to the design team and they can work on something for this, maybe after the sites are all rolled out?

A rough sketch or outline that the design team can work from is all I need! I'm not a database person (or an artist), so I'd hate to do either but knowing what looks "correct" from the start will help our designer get something that will look correct rather than looking like a circuit diagram or random lines and circles.

Please contribute your suggestion as an answer below.

Answer 1

Based on Crow's Foot notation:

Symbol reference:

Intended meanings as drawn (artistic licence employed):

• One (and only one) Database Administrators site
• Many questions
• Zero or many site achievements
• Zero or one featured meta questions (typically; of course right now we have two)

The far terminator is currently a circle. I guess this could be a diamond or something else from another ERD set, for variety. Or just remove it and the trailing line entirely.

Answer 2

Or perhaps something like this:

Answer 3

How about something like:

I'm sure the nice folks from Stackexchange can produce specs with exact dimensions and suchlike. If necessary I've got Adobe CS6, visio etc. and could knock up a model that's not based on someone's production system.

Getting the image to tesselate correctly down the left hand side of the page might need a bit of work.
