The colours in the image are rather difficult to distinguish. The image uses six basic hues at three different saturations, which are rather difficult to distinguish. JIP | Talk 20:04, 18 December 2011 (UTC)
- I have tried various colors but I'm afraid there are just too many countries to distinguish them all. Sure we could use additional symbols on the lines but they look pretty ugly. Maybe we should give an explicit hint that the lines are in fact ordered according to the country's latest figures? --spitzl (talk) 17:56, 30 December 2011 (UTC)
