This page shows some random data thematically displayed for Super Output Areas in Leicester and Leicestershire. If you have not used google maps much, try zooming out a long way (click on the minus sign) and then pan across to Europe or America. Its a joined up world.
Try zooming in on the City Super Output Areas. The boundaries are somewhat coarse and jagged, but they could be much more detailed.
