Because there was only a shitty graphic on the German Wikipedia Article on the Finnish parliament elections I decided to do my own. Please feel free to use them when you need it. You may find more information about the Finnish Party System here. The original data is from Statistics Finnland, whose people are helpful but don’t seem to know their own website very well.
