Thematic coloring is very useful for some kinds of maps. It's not very well-integrated yet, but this map already looks nice.

projection = equalarea
size       = 800 500
center     = 13 53
extend     = 27 19
name       = eu
background = political
borders
clabels
locale     = pl
colors     = eui.clp
