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. AFRIKAANSE OPSOMMING: Hoofkomponent-analise bi-stippings met gekalibreerde asse is gewilde en effektiewe visualiseerings tegnieke vir meerveranderlike data. Bi-stippings is soms moeilik om te navigeer as gevolg van die beknopte area in die data sentrale, asook die beperkings wat gepaard gaan met statiese grafieke. Die bipl5 pakket stel drie bydraes voor vir die bi-stipping: i) die automatiese ortogonale parallelle translasie van die asse tot die grens van die grafiek om die data sentrale minder beknop te maak; ii) superponeer interklas kerndighede op elke as om die verdeling van klas groepe in die data te ondersoek; iii) teken die finale grafiek in ’n onafhanklike en alleenstaande HTML leer met ingebedde reaktiwiteit. Hierdie artikel ondersoek die wiskundige en berekeningsimplementering van bipl5, en wys die funksionaliteit daarvan deur middel van ’n illustratiewe voorbeeld.
