mapper.js 2.4 allows you to add automatic area highlighting to image maps on your webpages (inc. export to SVG). It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, Safari and IE6+. On older browsers, it can use "jsgraphics" from Walter Zorn (if installed), else it'll degrade and your visitors won't notice a thing.
