ml" target="api">Overview</a> is just a matter of setting <a href="../api/symbols/Overview.html#observed" target="api">Overview.observed</a>
to refer to the <a href="../api/symbols/Diagram.html" target="api">Diagram</a> that you want it to show.  So there needs to be a DIV for your main diagram,
for which you create a Diagram in the normal manner, and a separate DIV for your overview, for which you
create the Overview in a very simple manner.
