An art director for AI agents that hate ugly charts

What it does

Lieflat Charts is a skill package for AI agents that speak the SKILL.md format—moxt, Claude Code, and Codex included. Hand it data and it returns interactive HTML charts, or full-page bilingual reports if you explicitly ask for them. The output is standalone HTML with editorial typography, motion, and structured whitespace rather than generic widget-like plots.

The interesting bit

Instead of a one-size-fits-all template, the skill auto-selects between three visual personalities—Lupi for slow narrative reading, Glance for instant dashboard scanning, and Basics for familiar chart shapes with refined detail—and picks a color system based on data structure. It essentially gives the agent a magazine art director’s taste without human micro-management.

Key highlights

• Three visual grammars: Lupi (editorial narrative), Glance (rapid judgment), and Basics (refined standard charts).
• Auto-selected color palettes: Mono fallback, plus Porcelain Blue, Palm Green, and Editorial Red; custom brand colors supported if specified.
• Twelve full-page HTML report templates in both Chinese and English, covering annual reviews, dashboards, posters, and research briefs.
• Interactive templates for networks, path data, and multi-segment flows.
• Native integration with moxt.ai, where the skill was designed and validated.

Caveats

• The README notes the smoothest experience is inside moxt.ai; other agents may need more context to reach the same output quality.
• It targets agent environments, not human developers looking for a drop-in charting library.

Verdict

Worth a look if you want your agent’s data stories to look like a designed publication rather than a spreadsheet export. Skip it if you need a programmable charting library for a human-coded frontend.
