SKD - Slovene Christian Democrats; ZLSD - Associated List of Social Democrats; SDSS - Social Democratic Party of Slovenia; LDS - Liberal Democratic Party; ZS-ESS - first of two Green Parties, separated after 1992 elections; ZS - second Green Party; DS - Democratic Party; SLS - Slovene People's Party; SPS SNS - a group of deputies, former members of SNS, separated after 1992 el SNS - Slovene National Party; ------------------------------------ The original problem had 3D xyz coordinates, but all values of z were equal to 0, and have been removed. This graph has 2D coordinates.
