Exploration of mortality in 3D surface The 3D surface plot shows a better view of the distance between the clusters for same selected of variables on mortality in the dataset shown in Figure 3 (Life expectancy in 1980, Life expectancy in 2001, Infant mortality rate in 1980, Infant mortality rate in 2001, Under 5 mortality rate in 1980, Under 5 mortality rate in 2001, Adult male mortality in 2001, Adult female mortality rate in 2001, Percentage of male over 65 years old 2002, Percentage of female over 65 years in 2002). Here distance between map units is represented by height value along the Z axis and color. It becomes easier to see the different clusters and view the distances between the different countries according to the select attributes related to mortality in the dataset.
