Hi, I'd like to fill an existing svg (or png) map with gradient colors. In detail: The file http://commons.wikimedia.org/wiki/File:Karte_%C3%96sterreich_Bundesl%C3%A4nder.svg should be filled with the population density data from this table: http://de.wikipedia.org/wiki/%C3%96sterreich#Verwaltungsgliederung choosing the right color saturation (or whatever). The final result should be something like this map: http://commons.wikimedia.org/wiki/Image:Bevoelkerungsdichte_-_Oesterreich.svg Is there a package or so for these two tasks (filling and color density ploting)? Thanks for your help, Thomas
