Cultural Map of the World (Inglehart-Welzel)
This is an application of a factor analysis plot, used in this case to display the 'cultural proximity' of several countries. This proximity is calculated based on survey scores on areas such as politics, religion and social life. The data is 'reduced' to some dimensions (displayed in the axis of the chart) and then plot according to how much they load in each dimension. This type of graph is used specially in qualitative research.
