    ENGLISH SUMMARY: Principal component analysis biplots with calibrated axes are popular and effective multivariate data visualisation tools. Biplots are however often complex to navigate due to cluttered plotting in the central data area, as well as die limitations that accompany static rendering. The bipl5 package proposes three contributions to the biplot display: i) automated orthogonal parallel translation of the axes to the boundary of the plot and declutter the plot center; ii) superimpose interclass kernel densities on each axis to investigate class distributions in the data; iii) render the final plot on a portable and standalone HTML file with embedded reactivity. This article considers the mathematical and computational implementation of bipl5, and showcases its functionality through an illustrative example.
