Tufte Report — Data-Driven Infographic Skill

Create standalone HTML reports that combine editorial narrative with interactive data visualization in Edward Tufte's style: high information density, minimal chart junk, typography-first design.

Design Philosophy

Tufte's core principles drive every decision:

• Data-ink ratio: every pixel of ink should represent data, not decoration
• Small multiples: repeat a design to show comparison, not animation
• Sparklines: word-sized graphics that live inside prose
• Layering: overview first, then detail on demand
• Integration: text and graphics share the same visual space (sidenotes, not footnotes)

The report should feel like a well-edited magazine feature — you read it top to bottom, narrative carries you through the data, and every chart earns its space by answering a specific question.
