Clustering was performed using agglomerative hierarchical clustering as implemented by the Plotly graphing package through their dendrogram function (plotly.figurefactory). The linkage criterion used was ward. The dendrogram was paired with a heatmap (plotly.graph_objects) of log2 fold change of metabolites. Source data were imported with the OpenPyXL package, and managed and transformed in a Pandas dataframe.
