Triangular Plot Map


Triangular Plot Map

Triangular Plot Mapping is useful in that it is able to display three dimensions or qualities of a given subject while also showing their relation to each other. In the example below, triangular mapping is used to show implications of correlations between skin color and genetic ancestry of West Africans, Europeans, and Indigenous people for biomedical research. From the triangle plot, it can be readily observed that the majority of humans come from some stem of West African descent.
