Annoyingly the map does not scale if you use something like
img to scale the image (at least in Firefox 188.8.131.52 on FC10).
but maybe there's a nicer way???
Note that IE(8) automagically uses the alt attribute of the area entities to do a tooltip on each area - if you want this sort of thing on other browsers, it looks like a DIY job. (Or maybe you can abuse the title attribute?)
