Combining clustering and graphical approaches

In this tutorial, we show the complementarity between a clustering method (HAC - Hierarchical agglomerative clustering) and a factor analysis approach for multivariate data visualization (PCA - Principal Component Analysis).

The aim is to obtain a better understanding of underlying concept organizing the data.
