## AntV chart-visualization skill

The embedded `SKILL_CONTENT` constant in `src/skill.ts` is adapted from:

- Project: `antvis/chart-visualization-skills`
- Source: `skills/chart-visualization/SKILL.md`
- Commit: `d168980d14218c2bf0cd153e111abd404c231482`
- Copyright: 2025 AntV Visualization Team
- License: MIT

The adaptation replaces the upstream `curl` workflow with the native DeepSeek Harness `antv_chart` tool, clarifies failure behavior, adds privacy guidance, and keeps the documented chart-selection and data-format guidance.
