My entry is an extension of the work I was doing representing the
election data; it adds in the Ordnance Survey Boundary Line data to
show the county council election results on a Google Map. Here's an
example of the 2009 results.
There's also a full map for 2005, but nothing for 2001 - the
boundaries changed in 2004.
Note that the map is likely to be very slow in Internet Explorer, but
it should be a lot quicker in Safari/Firefox/Opera/Chrome/anything
There's a link to a KML export of the data at the bottom of the map
for viewing in Google Earth or through Google Maps - this is a bit
experimental at the moment, you won't get filled-in shapes currently.
I've also added an map of the area to the individual result page.
Here's Leek Wootton.
I've started writing up the whole thing here...
