Edward Tufte's Visual Display of Quantitative Information — three executable skills (route, assess, render) backed by a VDQI-sourced principles reference. Scores graphics against Tufte's nine criteria 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.
