" summary

Argues that charts must be truthful and compact: keep the data-ink ratio high, remove redundant gridlines and legends, and label directly so users don’t have to look back and forth. Demonstrates Tufte’s lie factor with examples (a New York Times bar inflated ~15×, Napoléon’s march showing ~90% attrition from ~500k to ~10k), favors sparklines and small multiples for high-density comparisons, warns against 3D and decorative “ducks,” and notes common tools (Excel, chart libraries, animations) can produce either clarity or deception.
