Edward Tufte's Visual Display of Quantitative Information — two executable skills (tufte-critique, tufte-chart) backed by a VDQI-sourced principles reference. Critiques graphics against a nine-criterion VDQI rubric with named chartjunk species and a 13-entry catalogue of dissected failures, and renders per-genre charts (time-series, small multiples, quartile plot, range-frame scatter) plus a tufte-css HTML wrapper.
