factoextra vs NocoDB

factoextra supplies the fviz_* grammar most R users reach for when plotting PCA, correspondence analysis and clustering results. It sat effectively dormant from 2020 to early 2026, then shipped three releases in five months that resolved a six-year issue backlog, decoupled it from its original backends, and taught it to plot UMAP and t-SNE embeddings. The current version also reaches into tidymodels, plotting a PCA fitted inside a recipe or workflow directly.

The direction is from wrapper to visualization layer. as_factoextra_pca() turned the fviz_pca_* family into something that consumes coordinates from anywhere — cmdscale, vegan, a custom decomposition, a recipes step — rather than only FactoMineR objects, and the vignette on extending factoextra to new backends says the maintainer intends others to plug in. The embedding support shows the same care: no scree plot, no correlation circle, and a convex hull instead of a confidence ellipse, because an embedding does not preserve the metric an ellipse would assume.

With recipes and workflows already wired in, the next likely step is covering more tidymodels dimension-reduction steps (step_umap, step_ica, step_pls) through the same as_factoextra_pca() entry point rather than adding new fviz_* functions per method.
