Apply Tufte's Chapter 9 + Epilogue principles for the visual craft of a finished data graphic — the qualities of attractive displays, friendly vs unfriendly graphics, horizontal proportion and the golden rectangle, thin-line copper-plate craft, words/numbers/drawing integration, format selection, and the thesis that beauty is a by-product of clarity and data complexity. Use when judging or refining the look and technique of a graphic, not its data integrity or chartjunk count.

The six principles of analytical design from Beautiful Evidence — how to build evidence presentations that assist reasoning rather than decorate reports, why those principles are universal (from the first stone map to any future display), and how to distinguish analytical from decorative design.

How to design graphics that demonstrate causality rather than mere correlation, drawn from Tufte's analysis of the Snow cholera map and the Challenger O-ring disaster; use when building or critiquing any display whose purpose is to support a causal claim or policy decision.

Identifies and eliminates the three categories of chartjunk — vibrations, grids, and ducks — graphic activity that consumes ink, area, and attention while communicating no data. Use when auditing or designing any chart, dashboard, or data graphic for visual noise.

Tufte's analysis of how PowerPoint's bullet-and-slide format degrades analytical reasoning — the named deficiencies, the bullet list's three-relationship limit, density and pairwise-comparison thresholds, the Columbia case study, and the written-report/4-pager remedy — for use when designing, reviewing, or replacing any slide deck or analytical presentation.

Apply Tufte's principles for color in data graphics — the four functional uses, color's three dimensions, Imhof's four rules, palette strategy, contextual effects, and redundant coding — to maximize information density while minimizing color damage.

Covers Tufte's dual principle of data density AND data-matrix size (VDQI ch.8, pp.161-176) — the formulas, the typographic-density yardstick, empirical benchmarks across 21 publications, the Shrink Principle, three viewing depths, multifunctioning elements, small multiples, and the supertable — for designing, evaluating, or critiquing any statistical graphic.

Apply Tufte's data-ink ratio to strip non-data ink and redundant data ink from statistical graphics — through the two-pass erasure procedure, graphical redesign, and converting frame/tick ink into data — so the largest possible share of ink carries information.

Design data maps the way Tufte treats them in Envisioning Information — as the benchmark of information design and the densest, most multidimensional escapes from flatland — by increasing dimensions and data density, rewarding micro and macro reading, and letting the data question override cartographic convention.

Apply Tufte's overarching framework for putting multivariate data on a flat surface — the TWO goals (more representable dimensions, higher data density) reached through FIVE methods (micro/macro readings, layering, small multiples, color, space-time narratives) — when designing any chart, map, dashboard, table, or display that must carry more than two variables.

How evidence presentations are corrupted through effects without causes, cherry-picking, overreaching, chartjunk, and the rage to conclude — with detection methods for each, drawn from Beautiful Evidence ch. 6 (pp. 140-155).

Defines graphical excellence per Tufte's VDQI Chapter 1 — the five criteria, the ideas/time/ink/space formula, the four exemplary graphic forms, the substance/statistics/design test, and named failure modes — to apply when designing or evaluating any data graphic.

Apply Tufte's six principles of graphical integrity and the Lie Factor to detect, measure, and eliminate distortion in data graphics — use when designing, reviewing, or auditing any chart for truthfulness.

How to stack multiple information streams on a flat surface without generating visual noise — the 1+1=3 principle, the noise formula, figure/ground, weight hierarchy, grids, type placement, and color as a layering tool, with worked editing techniques.

Design and audit diagram connectors — links, arrows, causal lines — as differentiated evidence about each specific relationship (its type, direction, strength, certainty, and mechanism) rather than generic geometry, following Tufte's "Links and Causal Arrows" chapter in Beautiful Evidence. Use when building or critiquing flow charts, networks, webs, trees, org charts, project/parse trees, influence diagrams, or any graphic that ties nouns together with lines.

From Beautiful Evidence's "Mapped Pictures" chapter — turn any representational image (photograph, painting, drawing, micrograph, satellite or scientific image) into evidence by adding measurement scales, the universal x-y-z-t grid, labels placed on the image, and an explanatory mapping; and judge mapping theories by explanatory tightness and falsifiability rather than by eyeballing.

Design displays that read at two scales at once — the individual datum up close and the aggregate pattern from a distance — by layering immense detail so complexity rewards inspection without sacrificing legibility at a glance. Grounded in the "Micro/Macro Readings" chapter of Tufte's Envisioning Information.

Apply Tufte's principle of multifunctioning graphical elements — designing every visual component to carry several data functions at once via data-built marks, data-based grids, double-functioning labels, and the named design forms (range-frame, dot-dash-plot, quartile plot, white grid) that result.

Apply Tufte's principles for visual explanations of process, causality, and change — keeping images quantified (scales, labels, orientation), selecting the causally relevant axis variable, showing all data including zero-effect cases, enforcing spatial adjacency for comparison, representing motion and sequence in static displays, inverting magicians' disinformation tactics into honest design, using PGP narrative structure, applying the smallest effective difference, and avoiding faulty parallelism.

How to construct visual parallels that answer "compared with what?" — the mechanisms (position, orientation, overlap, synchronization, common content/track/centering), the spatial-vs-temporal choice, flap/superimposed/synchronized variants, direct labels over codes, and the named failure modes. Use when designing comparison views, before/after UI, diff displays, identification guides, or any layout whose job is to set two or more things side by side.

Apply Tufte's principles for warranted redundant and multi-channel visual encoding — riding the same variable on several perceptual channels to win robustness, separation, and accessibility, while avoiding the 1+1=3 noise that overlapping marks generate. Anchored in Envisioning Information's layering-and-separation chapter and the Swiss topographic map's four uses of color.

Apply Tufte's small multiples pattern — identical design structure, shared scale, and shared encoding across panels where only the data changes — to enable direct visual comparison across conditions, time, categories, or variables.

Design, construction, and reading of space-time graphics — graphical timetables and related forms that encode movement, speed, and scheduling conflicts by mapping spatial position against time on orthogonal axes.

Design rules, the typographic and density arguments, aspect-ratio math, variations, anchoring methods, and domain applications for Tufte's sparklines — intense, simple, word-sized data graphics embedded in prose, tables, and numbers.

Tufte's framework for content-responsive typography in analytical displays — how space and linebreaks make or destroy meaning, direct labeling over legends, data paragraphs over LittleDataGraphics, idiosyncratic paragraphs for memory retrieval, weight hierarchy, typeface choice, and annotation as evidence. Use when typesetting charts, tables, schedules, maps, labels, or any text that carries data. Draws on VDQI, EI, BE, and SWFE Chapter 2.

How to build "confections" — single compositions that juxtapose heterogeneous, real-and-imagined image-events to make an argument; use when designing explanatory posters, mixed-media dashboards, infographic narratives, onboarding scenes, kiosk/interface screens, or title/cover art that must reason rather than decorate.

Applies Tufte's full framework from Seeing With Fresh Eyes — the SEE/REASON/ACT triad, model criticism and remodeling, content-responsive typography, graphical sentences and stacklists, and data-analysis integrity — as named failure modes, comparison tables, do/don't pairs, and concrete numbers across all four chapters.
