This is a continuation of the analysis of the debris from the
space shuttle explosion.  In this example, the locations of the
individual pieces of debris are shown on a close-up map of 
several counties (each piece of debris is represented as a 
colored rectangle, with an id# as a label).  The rectangular
markers are color-coded, showing whether the piece of debris was
from the left wing, or the right wing.  The debris pattern 
clearly shows that the left wing broke apart first, and the
right wing did not break apart until the very end.
(This is not real data, but "plausibly real".)

The rectangular markers are created using annotated text with a 
colored box behind it, and the html= varaible adds an html charttip/
flyover-text to each marker indicating it's id# and exact longitude/latitude 
(using html 'title=' tag).  Also, 'href=' is used to add a "drilldown"
such that when you cick on a marker, it shows you a layout of the
wing debris (if I had additional pictures, this could actually link
to a picture of this particular piece of debris, and even show 
exactly where the piece came from in the wing).
