There are a lot of political maps on Wikipedia where each country is coloured depending of various things. On preview smaller countries are not visible.
SVG source is usually big, as it contains borders between all countries.
But when I view more than one such map, borders are usually the same and only colours differ.
How to avoid downloading almost the same map in SVG again and again and only download colouring and other essential details?
