"text": "This week, I encoded Edward Tufte's data visualization principles into an API. Then I let an AI agent try to pass it.\n\nI gave @ManusAI a CSV of women's bachelor's degree percentages across STEM fields (1970-2011) and one prompt: visualize this data.\n\nIt produced a standard chart. Correct data, readable axes, nothing wrong. But a legend box instead of direct labels. No annotations calling out the rise and fall of women in Computer Science. Default colors. This is what every AI agent produces right now.\n\nSo I pointed it at the Tufte Test, a quality standard I built in Truesight that checks charts against seven of Tufte's core principles. The API came back: fail on direct labeling and integrated annotations. Five other criteria passed.\n\nA quality standard gives an agent something a vague prompt never can: a precise list of exactly what to fix.\n\nManus revised on its own. Legend box became direct endpoint labels. A subtitle surfaced the key insight. An annotation marked the Computer Science peak at 37.1% in 1983. Two prompts total from me. Everything else was autonomous.\n\nAny AI agent that can call an API could do this. What matters is the pattern: encode expert judgment once, deploy it as an API, and every AI agent in your stack builds against it. Your taste becomes infrastructure at scale instead of manual review.\n\nThe Tufte Test is available as a template in Truesight if you want to try it on your own charts.\n\nFull writeup + demo video: https://t.co/Xkc9AK87xG",
