In reply to Leonid Batkhan.

We would definitely be interested in something like that, that kind of usability is exactly what we would like to do, we've just never had the tools to do it. At the moment we have to use what software we can depending on the size/ format of the shape file, so our recent publication mapping Higher Education Cold Spots (http://www.hefce.ac.uk/whatwedo/crosscutting/coldspots/) end up as a combination of static SAS maps, zoomable Google Maps and very much more user friendly Tableau maps. Will keep an eye out!
