Wikipedia apparently used out-dated data for Switzerland. The latest official statistics on gun deaths is available for 2010: http://www.bfs.admin.ch/bfs/portal/de/index/themen/19/03/02/dos/03.Document.139174.xls http://www.bfs.admin.ch/bfs/portal/de/index/themen/19/03/02/... According to this document, 24 persons were killed by gun in Switzerland in 2010. Switzerland has about 8'00'000 inhabitants, i.e., the there were closer to 2 deaths per 100'000 inhabitants and not around 6 as indicated in your diagram. Independent from the statistics, gun ownership and gun deaths have significantly decreased over the last 20 years. I take it for granted that wide availability of gun leads to a more often use of guns. In Switzerland, the reduction of the army's and tightened gun ownership legislation probably led to this decrease.
