Correlations between univariate variables: element length (including the three interpolated values), denticle height, pit depth, and distances between denticles. In each case, the diameter of the circle and its color is proportional to the strength of the correlation, estimated using the Pearson coefficient. Variables are order to a hierarchical clustering approach.
