Figure 5
Heatmap indicating the clustering and relative compositions of the VCs. Medals clustered according to the Euclidian distance between their compositions. Compositions were scaled so that the mean in each column is 0 and the standard deviation is 1. A low metal enrichment value indicates the corresponding medal has an unusually low composition of that metal relative to the other items analysed. The year, era and finite mixture modelling cluster of each VC is indicated on the right of the plot with the relationship between items within a cluster indicated by the dendrograms.
