The PCA projection can be enhanced to a biplot whose points are the projected instances and whose vectors represent the structure of the data in high dimensional space. By using proj_features=True, vectors for each feature in the dataset are drawn on the scatter plot in the direction of the maximum variance for that feature.

SpletPrincipal Components Analysis (PCA) Principal components analysis (PCA) is one of the most useful techniques to visualise genetic diversity in a dataset. The methodology is not restricted to genetic data, but in general allows breaking down high-dimensional datasets to two or more dimensions for visualisation in a two-dimensional space.
